I think that the big picture, in most elections, is missed by the majority of the populace.
Whether someone is Christian, Jewish or Muslim should not be the main concern. What should be the main concern are their character and their plans for improving the country.
Their plans for improving the country should be sound. That is to say that they should not rely on tax increases or tax cuts to improve things. Instead, they should rely on sound policies that spend our tax dollars responsibly. Unfortunately, so many politicians tell us how they are going to throw money at a problem. They speak of universal health care and the people's rights to it, disregarding the fact that no one has the "right" to health care. They assign "rights" and ignore the US Constitution. Anyone who does that is pandering and has no business in office.
As for character: Character is more important than the claimed policies of any politician. One who has no character will say what it takes to get into office and then do what he has to to maintain that office. I would much rather have someone I knew would follow what they say than one who would say what it took to get in and then do whatever breeze said was popular.
