Conservative? Now that is funny.
Using your logic Liz Chenny should be the next R nominee for president.
Huh? My opinion is that the Republicans should nominate conservative candidates who are skilled politicians.
Liz Cheney may be conservative (although she was consistently rated in the middle of the pack by conservative policy groups), but pissing off so many of your constituents that you lose in a blowout is not good political skills.
I will also note that long before she went anti-Trump, she was considered a middle-of-the-road Republican (at least by her fellow Republicans). While she took the far-right position on foreign policy, on domestic policy she was a moderate.
