But the one exception is Heller, the sole Republican senator defending a seat in a state that Hillary Clinton won. After failing to mobilize voters effectively around the GOP blockade of Merrick Garland two years ago, Democrats are determined to take advantage of their one chance to make a Republican pay for the party’s Supreme Court machinations.

Beating Heller is central to Democratic hopes of taking back the Senate in the future. And allies of Heller’s opponent, first-term Democratic Rep. Jacky Rosen, say the high court vacancy is already helping.

“We’re seeing this nomination supercharge her campaign,” said Ilyse Hogue, president of NARAL Pro-Choice America, which is backing Rosen and spending heavily to influence the Supreme Court nomination fight. “There is certainly a talking point out there that the right has mobilized on Supreme Court nominations in a way progressives have not, and that is simply no longer true.”
