You'd prefer an Obama?
I'll take Joe the construction boss, who stumbles putting a sentence together, but has a heart full of love for this country and the ability to fnd out what needs to be done and then get things done.
The moral luxury of living in a shared Christian culture has been over for decades -- since WWII. One administration is not going to be able to bring it back, no matter what gets promised. Tend to your own morality, work within your own community and church, and push for what you want; but try to avoid throwing away your vote if you cannot get an outspoken Evangelical nominated.
A lukewarm Christian with a mandate from a majority will get a lot more done than an ardent Chrisitan who barely squeaks by and then has all hell turned loose on him by the many minions of the devil alive in this society today. The nasty things being said about Justice Scalia's death by a disgracefully large contingent of detractors should tell you just how easy it would be for an openly professing Christian president to garner legislative support for moral issues.
Obama isn't an eloquent speaker either.
