People have a pretty good idea as to why they would vote for trump.
1) because he shits on politicians, who they hate
2) because he hates illegals (but will let the current illegals stay)
3) because he's rich and exciting and a celeb.
THAT is why trump's leading. He has been purposefully vague on his political positions. He's been rude and immature and claimed he'll do some things which aren't even covered under prez powers. But for reasons 1,2,3, repubs are jumping on his bandwagon. Most can't tell us trump was anti-gun, or pro-abortion, or that hilary sat up front at his wedding. They don't care, they just want a hero so bad.
