Mitch is perhaps the BIGGEST part of the problem. Not only did he succesfully block Trump from getting any of the agenda that the GOP ran on for 25 years, he has systematically used his PAC to fund RINO candidates whose only purpose is to block actual conservatives from winning elections for the GOP. He is the ultimate uniparty asset: a pretend conservative who makes you think the GOP is a real opposition party but who works tirelessly behind the scenes to oppose only the conservative base.
Yea, remember what he did to his fellow native Alabamian, Roy Moore in 2017.
