There are strategic moments that make sense. Liz Cheney (with no actual policy compromises) saying basically that, "I'm a Republican but Trump is a national security threat so I'm voting Harris" is strategically sound. Those who know Trump is a threat were already voting Democrat. Those on the fence or sitting out may have been persuaded by this bipartisan act (even though we all know we wouldn't want Cheney running domestic policy).

With respect to Massie, I'm glad he has carved out a sliver of morality on this one issue because Good vs. Bad isn't boolean; it's a gradient.

That said, there isn't a race in the country for these midterms where the Republican is better than the Democrat on the ballot.

(Also, Massie like Liz Cheney and Adam Kinzinger before him, already lost his Primaries so won't be in Congress anyway next year)
