I would argue that what they're doing is scaring the bajeezus out of the moderates and independents, as well as the Dems. Which should result in a lot more of them showing up at the polls to defeat Trump (just like last time).

Maybe - but I suspect it might be backfiring.

Good point. I think some people are genuinely concerned that Trump will try to become a Dictator (with 4 years to plan it and plenty of motivation from the criminal indictments). I doubt the current discussion will affect the voter turnout in 11 months, but it could affect the primaries that start in 7 weeks. Trump is far ahead, but Haley might be the tougher opponent for Biden.

In the first 2 primary states (NH and SC), Haley is leading among the non-Trumpers, and Trump has about 50%. Haley could possibly beat Trump if more candidates drop out.

The HarrisX poll (Nov 27)
Haley 55% Biden 45%
Trump 53% Biden 47%
DeSantis 51% Biden 49%
