Steven Waldman points out that despite the lashing Obama is getting from the left about Rick Warren, there’s a lot of angst about it on the right as well. These reactions from Free Republic are illuminating:

Pray for them, yes! try to convert them, yes! Recognize their authority over you, yes!
Support them and give them credence, no! Rick Warren is their to just
cover up the smell. Front man and a shill for a corrupt presidency.

Methinks Mr. Warren’s pride is getting the better of him. Giving the
invocation at a presidential inauguration IS a big deal, but I’m sure
that standing before Jesus on Judgement Day will make it seem less than
trivial.

Rick Warren is one of those new age, book author, get rich thanks to
Jesus like Joel Osteen – TV pastors. I thought Warren was decent but he
is a phony.

Geez…the False Prophet swearing in the Anti-Christ…how nice.

What Obama has in mind is to use religious socialists to move his socialist agenda.

Warren is a symbolic loss to the progressive left, but will probably be a material, tangible gain to mainstream liberalism. Evangelicals will notice and they will remember. What the progressive left needs to remember is that Obama was a candidate for the left, but will be a President for everyone.
