This, said Moore, makes the Democrats a "small tent."
Wait a minute. Two years ago, Moore worked hard to make the Republican Party a small tent. He actively raised money for an ultra-conservative primary challenger to Republican Senator Arlen Specter of Pennsylvania. The reason? Moore complained that Specter was not conservative enough -- he called Specter "a RINO Republican" (Republican In Name Only).
Moore has the right to try to knock off any Republicans he thinks aren't sufficiently conservative. But he's a total hypocrite when he whines about the Democratic Party not having "room" for people like Lieberman.
The only reason Moore was standing up for Lieberman has nothing to do with allowing diverse views within a political party. (Back in '04, Moore didn't want diverse views in the GOP.) It has everything to do with the fact that Lieberman is more open to tax cuts of various kinds than most other Democratic senators.
