Roughly 40% of voters always vote Republican and roughly 40% always vote Democrat. Its the moderate 20% in the center who elect our presidents. Now being moderate by nature they are going to elect a moderate for president. So its going to be a Jeb Bush or a Joe Biden. Never a Donald Trump. Another reason Trump cant win is that he has alienated all of the hispanic voters in this country and most of the women. So find another candidate to back if you are a Trump supporter.
