A person's religion should be an issue only if that person is shown to be the missionary of a particular church and there is reason to believe that he would take orders for governing from that church. Such concerns were expressed about JFK as the first Roman Catholic to be elected President. Would it be JFK who was President. Or the Pope? Those fears proved to be unfounded. I think they would be unfounded in the case of Mitt Romney as well.
But then there is no way to describe JFK as a "good" Catholic either.
The Constitution is quite explicit that there shall be no religious test for holding public office. It is also quite explicit that the federal government shall not meddle in people's religious views or how they wish to excercise them, nor shall the Church in any form have ability to dictate what government shall be. Still, we wouldn't want an Islamic cleric running on a platform of putting America under Sharia law no matter how much the Constitution says he can't do that.
(A point of clarification: Obama is a member of the United Church of Christ. His particular congregation is definitely committed to the advancement of black people as its primary focus, but there is no way to describe any United Church of Christ as 'evangelical'. It is by far the most radically liberal of all homegrown Christian denominations. It is not the same group as the group known simply as the Churches of Christ.)

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I?-
I took the one less traveled by,
And that has made all the difference.
