Liz Cheney for speaking out against Trump. Paul Ryan for compromising too much. Jon Huntsman for having adopted Chinese kids.
I too am a fiscal conservative who largely identifies as Republican. Alas, it's very hard for me to say that today's Republicans represent me. No one actually tries to balance the budget and it's all about incredible social wars that kind of doesn't matter. (Like complaining about the number of lesbians in modern cartoons or whatever).
The fiscal conservatives that speak up fail the Republican purity test and are consistently kicked out. Literally all of them.
The few remaining fiscal conservatives have converted into cult of Trump, like Graham, to keep their voters placated.
