I am saying this only because I dived recently a lot into the 2016 Republican Primary Exit Polls.
In New Hampshire 47 % of Republican & Republican-leaning Independents said that they were betrayed by their own Politicians, 51 % said they did not.
https://edition.cnn.com/election/2016/primaries/polls/NH/Rephttps://www.nbcnews.com/politics/2016-election/primaries/nh/The 47 % Number is very concerning. If you break that down to Votes who voted for Trump in 2016 37 % said that they felt betrayed by their own Politicians which fuelled Trumps NH Win and basically gave us Trump as Nominee.
This was uniquely confirmed in other Primary States in 2016 as well.
I unfortunately think if Mitch McConnell and Congressional Republicans keep selling out the Republican Base they will get Trump again in 2024.
