He may not be a conservative, but he is:
1) Competent
2) Angry
3) Fed up with political correctness
4) Fed up with America going down the drain
5) Fed up with other countries kicking America around
6) Fed up with jobs being sent to third world countries and third world countries sending their citizens here to take American Jobs.
I could go on. I want an angry, competent President who loves America. Conservatism usually follows from there.
Rowdy Roddy Piper is dead, but his most memorable line was: "I came here to chew bubble gum and kick ass and I'm all out of bubble gum."
We need a president like that.
Getting angry is the way individuals climb out of depression. The whole country needs to get angry at the same things Donald is, and that you listed in your post: PC, American decline, horrible foreign relations, bad trade deals, destructive immigration and invasion.
