Seeing that picture reminded me his kids are biracial. So to add to this fatherhood moment: he also supports a man who doesn't respect someone of mixed heritage, the very thing his own kids are.
It's not cognitive dissonance, it's wilful suspension of the truth and the reason politics are driving wedges into our families and friends.
Lastly, I'm not a conspiracy theorist but if another country wanted to destroy us from within this seems like a good way to do it.
I'm not a conspiracy theorist, either, but my preferred suspicion is that it's aliens. They've tried a number of techniques, from implanting mind-control devices (Mitch McConnell and the way his face carries a look of horrified disgust at the things they make him do) to direct infiltration by putting one of their agents in an ill-fitting human suit (Ted Cruz). Ultimately, they seem to have given up the finesse approach, and settled on lobotomizing humans with existing personality disorders to create a RAID (redundant array of inexpensive dipshits) to simply overwhelm our system of government.
It's the only explanation that really makes sense to me.
Could happen that way, but I keep going back to the future timeline where fascists take over the US, fuck everything, decide war is the solution, then China puts them back in their place and reign as the world's super power for the next 200 years.
