Yeah and Ronald Reagan and all those Republicans who supported protectionism before him were commies too. Oooh, such a dirty word hah?
You do it because you are a "useful idiot" on the subject. You actually believe the government should control private arrangements for the benefit of some. That individuals should be forced to give up rights so some "greater good" (which really isn't) can be served.
And Republicans are just power seekers, like Democrats. Best not to fall in love with them either.
