"That's not going to work."
I agree that there's a personality cult around Trump, however Jeff Sessions, who Trump berated got 40% of the vote in Alabama. So that tells me that ~50% of GOP voters are rational. But resorting to MSM talking points is not going to work for a Republican primary. All Cheney has to get is a majority of that vote, which might be substantially below 50% given the number of candidates. I think she can do it if she attacks Trump on policies, not on overblown Jan 6th accusations, which most Republicans are tired of. Frankly, Jan 6th just shows more of Trump's incompetence in that he's didn't even understand that storming the capitol would not keep him in power, even if 100% successful.
