Doesn't matter right now if the Repubs kick all their moderates out and replace them with rightwing tongue talking loons. The democratic party doesn't have the ability to woo the moderates to their party because they have all the leftwing, treehugging, government interferers who will control the party in primaries. Between the two, moderate republicans are going to vote for fiscal conservatives and hold their nose on social issues. Dems fool themselves if they think any different.
