We've got a large pool of candidates to choose from this time. I'm going to vote for either Rand Paul or Scott Walker depending on how things go. Donald Trump is not a serious candidate imo, same as last time.
The conservative pool this time around isn't pathetic like it was in 2012, and the only serious candidate from the liberal pool seems like Bernie Sanders. It's very likely that we'll have a republican in the whitehouse, and my guess is that it won't be Donald Trump.
