Eh this is insanely off topic, but I'll take a crack at it. First off, realize that primaries don't even start until February. It's way too early in the race for me to believe Trump will remain a top contender. Honestly, I think he has a lot of money to throw around right now and garners a lot of media attention for saying ridiculous things. He has the most publicity right now which might be skewing the polls right now. You're getting lots of extremely conservative people bumping Trump in the polls while the moderates are probably not participating. Basically, lots of bark and hopefully not much bite in the future.
