Future of the anti-Trump GOP voters

[Canis]

of the ones I know all three are registered republicans and good friends of mine ive had a lot of conversations with them about politics recently to get their view on things
1. McCain-Romney-Johnson basically a libertarian politically used to vote straight R downballot but after Trump got elected in 2018 voted Republican at the state level (except when the republican nominees for statewide office where crazies) and voted Democrat federally Already voted for Biden said he plans on registering as NPA soon depending on how the GOP goes may return but if it continues to be Trumpy will likely continue voting for Democrats
2. McCain-Obama-Clinton Voted downballot republican all her life but after Trump won she voted straight D in the midterms and will vote straight D this year is likely going to register as a Democrat as she feels abandoned by her party
3. McCain-Romney-Johnson voting for Biden this year voted straight GOP in the midterms says will almost certainly remain in the GOP
its interesting to me that the never trump GOP voters I know who voted for Johnson and are going to Biden this year are like the southern democrats who voted for Wallace in 68 and then pretty much went to being straight GOP voters (some of which with the exception of Carter and Clinton) I predict that they will split three ways between becoming Moderate Democrats Independents and trying to stay in the GOP and reform it.
