>> I'm here today to tell the truth.>> Public support for President Trump's Supreme Court pick is slipping as the FBI looks into allegations of sexual misconduct. But Brett Kavanaugh scorched Earth confirmation battle may pay political dividends for Republicans as they try to keep their hold on the Senate in next month's elections.
>> I'm Andy Sullivan in Washington, where Republicans are seeing a clear trend, the Kavanaugh confirmation battle is galvanizing GOP voters who believe that a good man is being unfairly smeared. This trend is especially apparent in the handful of states that are likely to determine which party controls the Senate next year.
>> Kavanaugh has got to go.>> New opinion poll show that more Americans now oppose Kavanaugh than support him nationwide, but his support is rising among Republican voters.>> Thank you all so much.>> That could help Republican Senate candidates like Marsha Blackburn, who campaigned with Trump on Monday night.
>> She's all about Tennessee values.>> She's in a tight race with former Democratic Governor Phil Bredesen.>> Democrats are willing to do anything, and to hurt anyone to get their way, like they're doing with Judge Kavanaugh.>> Boo.>> The surge in GOP enthusiasm from the Supreme Court fight could make life difficult for Democratic Senators like Heidi Heitkamp, who's seeking reelection in conservative North Dakota.
She's facing a stiff challenge from Republican Kevin Cramer. A new batch of polling shows that North Dakota voters support Kavanaugh. And conservative groups are amping up the pressure, running TV ads urging Heitkamp to vote yes on his nomination.>> Now Senator Heitkamp has a choice. Tell Heidi Heitkamp, you'll never forget how she votes.
>> Similar ads on are on the air in deep red West Virginia where Democrat Joe Manchin is running for re-election.>> Democrats almost certainly need to win these three races in Tennessee, West Virginia and North Dakota if they want to win control of the Senate and the Kavanaugh confirmation battle could be hurting their chances.
Most Democratic Senators have already said they're gonna vote no. But Manchin and Heitkamp face a much tougher choice. If they vote to confirm Kavanaugh, he's almost certainly headed to the Supreme Court. If they vote no, they could lose their seats, and ensure that Republicans retain control of the Senate next year.
