Seven states' Congressional delegations (both House & Senate) lack any Republicans.  Only one state's delegation is devoid of Democrats.

Can you name them?

Answers after the jump.  Otherwise, treat this as an open thread.

No Democrats:
-Wyoming (Enzi, Barrasso, Lummis)

No Republicans:
-Connecticut (Dodd, Lieberman*, Courtney, DeLauro, Larson, Murphy, Himes)
-Hawaii (Inouye, Akaka, Abercrombie, Hirono)
-Massachusetts (Kennedy, Kerry, Capuano, Delahunt, Frank, Lynch, McGovern, Markey, Neal, Olver, Tierney, Tsongas)
-New Mexico (Bingaman, Udall, Heinrich, Lujan, Teague)
-North Dakota (Conrad, Dorgan, Pomeroy)
-Rhode Island (Reed, Whitehouse, Kennedy, Langevin)
-Vermont (Leahy, Sanders*, Welch)
*Lieberman and Sanders, while not Republicans, are not Democrats either, though they caucus with the Democrats.

Interesting follow-up trivia:
-Though Wyoming's Congressional delegation is all-Republican, Wyoming has a Democratic Governor.
-Though the Congressional delegations of Connecticut, Hawaii, North Dakota, Rhode Island, and Vermont all lack any Republicans, all five of those states have Republican Governors.
-Despite having an entirely Democratic Congressional delegation since January 1997, Massachusetts had a consistent string of Republican Governors between January 1991 and January 2007.
-Despite currently having an entirely Democratic Congressional delegation, New Mexico's Congressional delegation was majority-Republican as recently as five months ago.  Republican Senator Pete Domenici retired as was replaced by Democratic then-Congressman Tom Udall.  New Mexico's two other Congresspeople, Heather Wilson and Steve Pearce, both Republican, both also ran for Domenici's seat, lost, and were replaced by Democrats.
