Here's why the Democrats will in the Presidency in 2016.
1) Republicans have so badly poisoned their brand with minority voters.
Romney won an overwealming 59% of White Voters in 2012, the best showing since Bush-41 in 1988 (who won 60%). But minorities are now 30% of the electorate, and Romney only won 6% of the black vote and 29% of the Asian and Hispanic vote.
2) Women won't vote for them. Romney won Men 52- 48. But Obama won women 55-45. The fact the GOP keeps trying to slut shame women who have abortions and use birth control really doesn't help their brand.
3) The electoral College favors Democrats - The fact is, in the last six elections, a group of 20 states has voted consistently democratic, for a total of 242 Electoral votes. An additional three states have voted for the democrat 5 out of 6 times for another 15 EV's. That gives them 257 out of the 270 they need to win.
That means the Democrat has to merely win one or two other states in order to get over top - Florida (27) Ohio (20) Virginia (13) North Carolina (15) or the combination of Colorado and Nevada (9+6) would do the trick. The GOP, meanwhile, has to win all of them to win. The Demographics of all those states are leaning more blue than red as time goes on. For instance, the economic crisis in Puerto Rico instigated by their creditors means more people are moving from their to Florida.
4) The Republicans are a bunch of assclowns! Historically, the GOP has run candidates who have run before. They've been vetted. The top three current candidates have never held political office.
