Should Liberals Trust the President?

Interesting. In this piece, Mort Kondracke argues that liberals should bank on Miers being everything the President says she is.

Democrats ought to be taking Bush at his word - that he knows Miers' mind and heart very well. If they don't like what Bush stands for, they almost certainly won't like the way Miers will vote on the court.

How ironic would it be if liberals end up "trusting" the President more than conservatives do?
