I like the party line vote. In and election like 1994 and possibly this year, it gets lots of incumbents thrown out of office at all levels of government. In 1994 it destroyed the DemocRAT farm system in much of the county. Not only were incumbent DemocRAT congressman removed but also wannabes who might have run for congress over the next decade or so were denied incumbency in lower levels of government that would enable them to climb up to higher levels in later elecitons.
I think it also gave it to the Dems 2006 and look where it got us.
