Hillary Clinton has lost her lead over Donald Trump in Florida and Pennsylvania and ties the real-estate mogul in Ohio on the eve of the Republican convention in Cleveland, according to new polling.

Quinnipiac’s Swing State Poll focuses on the three states because since 1960, no candidate has won the White House without taking at least two of the three states. Democrat Clinton had an eight-point lead over Republican Trump in Florida in June, but now trails him with 39% to his 42%. In Ohio the race is tied at 41% and in Pennsylvania, Trump is at 43% to Clinton’s 41%. Clinton led Trump by one point last month in Quinnipiac’s Pennsylvania poll, and the Ohio race was tied in June at 40%.

A Clinton spokesman tweeted after the polls came out that the campaign knows battleground states “are going to be close til the end.”

Trump says Ginsburg should resign: Trump’s feud with Supreme Court Justice Ruth Bader Ginsburg, meanwhile, is getting nastier. Early Wednesday morning, he called for her to resign. In a tweet, he said her “mind is shot” and that she should quit the high court. ABC News has more on the war of words between the two. Ginsburg has called Trump a “faker” who lacks consistency for not releasing his tax returns. Here’s Trump’s tweet:

Clinton’s VP choices, detailed: Both Trump and Clinton are expected to announce their running mates soon. The Associated Press writes Trump has narrowed his list to three contenders. Clinton’s is for the moment more wide-open. National Public Radio has mini-biographies of eight potential choices, including Sen. Sherrod Brown of Ohio and Rep. Xavier Becerra of California. Not mentioned, however, is James Stavridis, a former four-star Navy admiral. He is reportedly another contender.

How Clinton, party differ on Wall Street tax: The Democratic Party’s proposed 2016 platform supports a financial transaction tax on Wall Street. But as Bloomberg writes, Clinton is focused on a narrower approach that isn’t likely to target big banks. Clinton and her advisers propose taxing some high-frequency traders who spam markets with thousands of orders they later cancel. But that would affect a small number of firms and Clinton isn’t likely to expand it to a tax on all trades of stocks and bonds, Bloomberg writes, citing senior policy analysts familiar with her campaign.

What’s in, out of the GOP platform: A border wall is in. A ban on AR-15 assault rifles is out. The Washington Post reports on the writing of the Republican Party’s platform, a final draft of which will be presented for ratification at the convention next week. The Post says the GOP moved closer to firmly embracing a series of staunchly conservative positions on abortion, gay rights, gun rights and immigration reform. The platform committee endorsed a border wall that would cover “the entirety of the southern border and must be sufficient to stop both vehicular and pedestrian traffic.” And the committee opposed a proposed ban on AR-15 assault rifles and restrictions on the size of ammunition magazine clips.
