The Note: Kavanaugh’s fate rests on vanishing middle Of the 100 senators, easily 90 – perhaps upwards of 95 – know how they'll vote.

The TAKE with Rick Klein

This is a hyperpartisan moment. But the only votes in doubt are a handful in the middle – those for whom the partisanship of the moment is noise, or worse.

Of the 100 senators, easily 90 – perhaps upwards of 95 – know exactly how they will vote on Brett Kavanaugh's confirmation to the Supreme Court.

Partisan grooves have only deepened in advance of Thursday's hearing. President Donald Trump as well as top Senate Republicans and Democrats have been making their positions – and how strongly they feel about them – more clear, without hearing a public word from Christine Blasey Ford.

If this was just about confirming a nominee, the only audience that matters are a few retiring Republicans, a couple of red state Democrats, and a pair of GOP moderates. "The conversation is not rational on either side," one of those moderates, Sen. Lisa Murkowski of Alaska, told The New York Times.

It highlights a paradox of this moment: Kavanaugh will or will not serve a lifetime appointment on the Supreme Court based on the judgment of a few people who occupy the center.

But the political conversation is being driven inside the parties' bases, where this showdown carries outsize weight as a galvanizing issue. Thursday's hearing may look like a search for answers, yet most of those directing the questioning know what they want to hear and how they want it heard.

The RUNDOWN with MaryAlice Parks

Executives from some of the world's largest technology companies will testify (again) on Capitol Hill Wednesday, including representatives from Apple, AT&T, Google, Twitter and Amazon.

"Consumers deserve clear answers and standards on data privacy protection," chairman of the Senate Commerce Committee, Sen. John Thune, R-S.D., wrote announcing this week's hearing.

But it's not just data privacy on the list of potentially tough questions. Expect the executives to be grilled on how their companies are handling fake news, election security, influence from foreign state actors, as well as political bias in their algorithms and workplaces.

Conservative politicians and activists continue to cry foul and have ramped up accusations against the tech companies, arguing they demote right-wing voices.

The hearing comes on the heels of a meeting Attorney General Jeff Sessions held with state law enforcement officials Tuesday in California to discuss the size and power of tech giants and subsequent consumer protection issues.

A senior Democratic aide told ABC News one senator on the committee plans to ask Amazon specifically about its facial recognition tools.

The TIP with Lissette Rodriguez

The latest polls out of Florida's tight Senate race show Democratic Sen. Bill Nelson pulling ahead– a change from polls earlier this month showing a dead heat.

Nelson has a 7 point lead over his Republican opponent and current Gov. Rick Scott, according to a Quinnipiac poll conducted from September 20-24. The poll has a margin of error of plus or minus 4 percentage points. An NBC/Marist poll, also out Tuesday, shows Nelson ahead by 3 points, 48 percent to 45 percent, within the margin of error.

One reason for Nelson's advantage could be his popularity with Hispanics, who make up almost one in five eligible voters in the state, according to the Pew Research Center.

While Scott led with Hispanic voters in an early September Quinnipiac poll, 59 percent to 39 percent, Nelson is now ahead with those voters, 61 percent to 39 percent. That's despite Scott's efforts to deliver bilingual speeches and distance himself from President Trump in Spanish-language television ads.

Nelson's lead now is comparable to what he had in exit polls from his 2012 Senate race, when he won the Latino vote 59 percent to 37 percent -- a key factor in his overall 13-point victory six years ago.

And although there are still 41 days until the midterm elections, the Quinnipiac poll shows 94 percent of Florida's likely voters already have their minds made up on the candidate they want – with health care the most important issue.
