Last Sunday, Hillary Clinton was enjoying a 12 point advantage over Donald Trump in the ABC New/Washington Post tracking poll, but seven days later, that lead has shrunk to just one point.

Additionally, about one-third of likely voters told pollsters they're now less likely to support the former secretary of state because of James Comey's announcement that the FBI was again looking into the Democrat's emails.

Even before this news, the battleground state of Florida was looking very much in play, with a new New York Times - Siena College poll showing Trump four points ahead and the Real Clear Politics polling average stating that Clinton and Trump are tied in the Sunshine State.

Hillary Clinton's (left) 12 point lead dissolved to just 1 point over Donald Trump (right), says an ABC News/Washington Post poll, which clocked the latest email developments

One week ago, Hillary Clinton was a full 12 points ahead of Donald Trump, now she's just 1 point ahead of her rival with just nine days to go before voters head to the polls

Other battleground state polls contains better news for the Democrat, who had a fairly smooth week on the campaign trail, until Friday's news put her campaign in disarray.

The ABC News/Washington Post poll reflects voters' views on the most recent email controversy, which stems from a separate investigation of Anthony Weiner, who DailyMail.com reported had been sexting with a 15-year-old girl.

Comey wrote a letter to lawmakers on Friday informing them that emails relevant to the probe of Clinton's private email server had been found.

Today CNN reported that the Justice Department and the FBI are in talks with lawyers for Weiner's estranged wife, Huma Abedin, a top Clinton aide, seeking permission to go through emails relevant to the Clinton investigation, found on the disgraced ex-congressman's computer.

On Sunday evening, NBC reported that the FBI now has a warrant to read the thousands of emails.

Sixty-three percent of likely voters said this latest development will make no difference in how they vote.

Donald Trump is making gains in Florida, with a New York Times poll showing him 4 points ahead and an NBC poll showing him just 1 point behind Hillary Clinton

Those who said the email reveal made it less likely for them to vote Clinton are overwhelmingly Trump supporters, pollsters noted.

The new polling also shows that there's a chance third-party hopefuls Gary Johnson, the Libertarian, the Jill Stein, from the Green Party, could indeed have a 'spoiler' effect, with Clinton leading Trump by one point – 46 percent to 45 percent – in a four-way race, with Johnson receiving 4 percent and Stein garnering 2 percent.

However, when it comes down to just Clinton and Trump, she has a 3 point lead over the Republican nominee, the ABC News/Washington Post tracking poll found.

Looking at individual battleground states, the New York Times - Siena College poll shows Trump 4 points ahead in Florida, while NBC's Sunshine State poll has Clinton 1 point ahead, 45 percent to Trump's 44 percent.

In a NBC News/Wall Street Journal/Marist Florida poll taken earlier this month, Clinton had been ahead by 3 points in a four-person race.

Trying to make up for lost ground, Clinton appeared last night in Miami with Jennifer Lopez and the pop star's ex-husband Marc Anthony and has made a number of campaign stops in the state today.

NBC News also conducted polling in North Carolina, a state that went for President Barack Obama in 2008, but his Republican challenger Mitt Romney in 2012, and found Clinton to be a more comfortable 6 points ahead, 2 points higher than she was up by last month.

In a four-way race, Clinton now receives 47 percent of the North Carolina vote, compared to Trump's 41 percent.

Before Friday's revelations, Clinton's appearance in North Carolina with first lady Michelle Obama brought the campaign a lot of positive headlines. Bill Clinton was also in the eastern part of the state engaging in a two-day bus tour.

CBS News also polled North Carolinians and found Clinton to be ahead, but by only 3 points.

CBS News polling also found that Clinton was up by 8 points in Pennsylvania, a state that Trump had hoped to turn blue thanks to its many white, working class voters.

She's also up in Colorado by 3 points as well.

Arizona, usually a reliable red state that looked like it could be turning blue, is for the moment still in the Trump column, according to the CBS News poll, which showed Trump 2 points ahead.

Interviewing for these surveys was done before Comey's letter was sent to congress, thus reigniting Clinton's emails as a political issue in the presidential campaign.

CBS also interviewed voters from 13 battleground states more broadly about the email developments.

Word traveled quickly, pollsters found, with eight in 10 voters saying they had heard about it by Saturday.

And as quickly as word traveled it became a partisan affair, with Republicans suggesting that bad things would be found in the trove of new emails, while Democrats suggested that the story was being overblown.

About one-third of Democratic battleground state voters, considered the FBI's moves to again probe Clinton on her emails a bad thing, but it wasn't bad enough for them to change their votes to Trump, who they believed to be far worse.

Just 5 percent of Democratic voters say it could make them less likely to vote Clinton on election day.

Among voters overall, 71 percent said the news would not change their thinking.

Similar to the ABC News/Washington Post poll, the majority of those who said they would be less likely to vote for Clinton over the email news were Republicans and thus Trump backers anyway.

Fifty-two percent of battleground state voters expected that the emails would contain 'more of what we already know,' while 48 percent expected the emails would reveal damaging things about the Democratic nominee.

The latter group was largely made of Republicans.

Finally, USA Today produced a new poll, in conjunction with Rock the Vote, of the youngest demographic of voters, those 18 to 34-years-old.

While millennials' support for Clinton over Trump is still robust, she lost ground in the last two weeks, going from 68 percent to 62 percent.

Trump, in the meantime, gained 1 point with the voting bloc.

Millennials' support for the two candidates is interesting in that Clinton has an edge with voters of all races. In the greater electorate, she overwhelmingly wins the support of black and Latino voters, but trails behind Trump by a handful of points.

White millennial voters, according to the new poll, support Clinton 57 percent to 27 percent. Black millennial voters support Clinton 84 percent to Trump's 6 percent. While Latino millennial voters support Clinton 66 percent to 19 percent. Additionally, Asian millennials supported Clinton 67-to-15 percent.

Hillary Clinton is a hit among millennial voters, polling finds, winning a majority of every race of young people and even winning more support from young men than young women

Thirty-four percent of millennials said that President Barack Obama's endorsement of Democrat Hillary Clinton was 'very important' to them, while just 10 percent said the same thing of Paul Ryan and Rudy Giuliani's support for Republican Donald Trump

The youth vote doesn't demonstrate the 'gender gap' on display in the rest of the electorate either, with Clinton actually earning a higher percentage of support from young men, 56 percent, to 43 percent of young women.

In an effort to rally her supporters and ensure good turnout on election day, the Clinton campaign is deploying a number of surrogates to swing states over the next week.

President Obama will campaign for his former secretary of state in Ohio and North Carolina, which is noteworthy because millennials suggested his endorsement has impressed them the most.

Thirty-four percent of millennial voters ranked Obama's endorsement of Clinton to be 'very important,' which ranks higher than the 31 percent of millennials who said their parents endorsement of a candidate was 'very important.'

Sen. Bernie Sanders, Clinton's Democratic primary rival, is scheduled to make campaign stops in New Hampshire and Maine. Twenty-six percent of millennials surveyed said Sanders' support of Clinton was very important, which was higher than the 24 percent surveyed who suggested their friends' support of a political candidate matters a lot.

Trump, on the other hand, doesn't have surrogates who necessarily compel young voters to support the Republican nominee. Just 10 percent of millennials found the endorsements given to Trump by House Speaker Paul Ryan and former New York City Mayor Rudy Giuliani to be 'very important.'
