Pragmatist, Politician, or Both?

I'm torn about Rick Warren being selected by Obama to give the invocation at his inauguration. On the one hand, I wish Obama had picked someone who was supportive of homosexuals and a woman's right to choose. On the other hand, it shows Obama's willingness to pitch a really big tent. It displays pragmatism and--dare I say it?--Machiavellianism. Perhaps we progressives have managed to find a leader who is tough and realistic enough to lead.

At least, that's what I'm hoping. It would break my heart to find out that Obama is just another politician.
