[Psalm 73]

"...at the very least, it comes off as sounding hypocritical."

There are two different world-views here, the secular-humanism of the "lock-step" Democrats, and the Biblical-world-view of the Christian Conservatives.
Sure, there are a lot of grey areas, not many things are black-and-white (although some things must be in a Biblical world-view).
If one has no belief in God, and/or thinks the Bible is gibberish, than you would feel more comfortable as a Dem or a Libertarian.
Why is it intolerant when those with a Biblical world-view would prefer the candidates that they give thier money and time to, to be like in mindset?
Setting standards IS NOT hypocritical - it is realistic, unless you're a member of the NEA.

The problem is that there are more than just the two world views you mentioned. And no single view is held by a majority (>50%). This is one of the things that makes America great. The problem is creating a coalition that garner a majority of the vote. One can set standards, as you say, but this may end up alienating a significant set of people that would otherwise have voted Republican.

Instead of forcing a single view, our energy should be spent promoting the benefits of our view, finding commonality with other views, etc.
