I think Trump would make a really funny and serious candidate to run against President Obama. He is funny, but also at the same time can be serious about other issues, I can only imagine what the debates would be like between Donald and Barack, I would actually tune in, kick back, and have a beer.
Trump has way too much baggage. Multiple Bankruptcies, multiple wifes, deferrments from Vietnam, failed business ventures like Trump Vodka, Trump Airlines, etc. He wouldn't get the nomination, plain and simple. He bounces off the walls too much and says some of the most ridiculous things. If anyone heard him on Chris Wallace's show, he suggested that we go in a steal an oil field from Iraq saying it wouldn't be more like reimbursing ourselves.....
Mitt Romney or Ron Paul would be the best choice. No Sarah Palin near either one of them. Get someone like Elizabeth Dole if they want a female Vice President. No more wildcard far right Republicans....time to swing back over to the moderate and sane.
