Liz Cheney however occupies absolutely zero space in the public's mind as anything

Then even if one grants the lib the full sociological ground (which is an absurd thing to do), this is still a bad idea because how is this nobody going to match up against Trump? Trump could throw some red meat to his base with the MyPillow guy or throw some red meat to the politics freaks with Senator Ted Lasso who went to Mexico when it got cold and they'd eat that shit up. Any moderate republican would see Ted Lasso as the unity ticket between 101.5% Hitler and the establishment politicians.
