absolutely right. The Democrats who have changed to Republican have done it honestly, not like this. He should be forced to resign.
Not always. Richard Shelby switched parties in 1994 and didn't run as a Republican until 1998. Ben Nighthorse Campbell switched in 1995 and didn't face the electorate again until 1998. Strom Thurmond switched mid-term and didn't resign. There's enough of that going around on both sides of the aisle.
