There are plenty of claims made by very educated historians that suggest that America was founded on Christian ideals.  Mitt Romney was ostracized for being Mormon.  Even Barack Obama had to assert his Christian faith after accusations that he is a Muslim.
Is our country founded on Christianity, or on religious tolerance and freedom?  How can a person's religious persuasion have an impact on what type of politician they would make?  Do you think it would ever be possible for a Muslim or an Atheist to become president?

All good points.  As far as your last point, Devoidless, I'm not sure that people are actually wanting to advance their religion so much as they just feel like they have something very huge in common with that candidate.
But then we come back to what I think is an unanswerable question of what makes someone a Christian.  People are probably just too stupid to realize that just because someone claims the same religion as them, it is not very likely that they will share very many important goals or motivations.
I was also thinking about America's war on "tyranny and oppression."  We want people to have a more democratized government but we don't try to change their religion.  If leaders thought that current democratic ideals or laws would be impossible without the teachings of Christianity, wouldn't it be also necessary to change a country's religion?

The Ideas of a christian:
Politics should be more diverse. I don't think it is right that some great candidates don't get a chance. I hate prdjudice, even if it is beneficial to me. I don't believe that it would matter if a different religeon were president, because it won't really affect the way I live. People are stupid, a person is smart. The politicial will appeal to christians and get his way. He wins people, he wins.
