Activists against President Trump’s Supreme Court nomination, Brett Kavanaugh, being confirmed have raised more than a half million dollars to fund a challenger for Sen. Susan Collins if she votes for him.

He is seen by many on the left as a real threat to LGBTQ rights, women’s rights, and Obamacare.

The Maine Republican has met with the nominee and said he assured her he sees Roe v. Wade as “settled law.” That issue of a woman’s right to have an abortion has become an even bigger issue during the Senate hearings after an email was released wherein Kavanaugh, then a White House aide in the George W. Bush administration, objected to an op-ed calling Roe v. Wade settled law, and asking for that passage’s removal.

“I’m always concerned about accuracy, and I thought it was not an accurate description of all legal scholars,” he told Sen. Diane Feinstein when questioned about it. Collins, for her part, has said she doesn’t believe the contents of the email contradict his assertions that the right for a woman to get an abortion is settled law.

Still, Collins has stood in the way of the GOP’s attempts to destroy Obamacare, and this, plus her stated pro-abortion rights stance, has left some hoping she will vote against Kavanaugh even if she has been making statements that sound as if she is leaning towards a “yes” vote.

Additionally, the Trump nominee has refused to say if he thinks the Supreme Court’s ruling legalizing marriage equality nationwide was correctly decided, and also wouldn’t say if it should be illegal to fire someone over their sexual orientation.

At time of writing, the fundraiser, hosted by Crowdpac, has raised more than $650,000, from nearly 25,000 donors.

“The people of Maine have made it clear that they want you to vote NO on Kavanaugh, and we’re counting on you to do the right thing,” the fundraising site reads.

The campaign is being led by activist Ady Barkan and initially had a goal of $500,000, which has now been raised to $1.3 million. Collins is not up for reelection in this cycle, but will be facing reelection in 2020. If she votes against the nomination, the money raised will be returned to those who donated, the site states.
