Which candidate has the best chance for the Presidency?
1. someone who is (relatively)poor - I don't think this is such a big deal. Yes, you have to have financial backing to run for President, but as for it being an issue among constituents, I don't think it would be.
2. someone from an ethnic minority - Colin Powell!!!
3. a female - So I'm biased, but I think a woman should be President at some point

As long as it isn't Hillary Clinton, that is.

Can we say Elizabeth Dole?
4. a non-Christian - It depends on what type of "non-Christian" they are. But I find it unlikely that they would be elected (especially in the South)
5. a homosexual person - I personally do not think this will EVER happen.
