Both parties like to blame the other for failing to exercise independence in Congress. Their supporters blame the members of the opposite side for excessive partisanship which keeps Washington DC from accomplishing anything for the people. The Washington Post decided to take a look at the 110th Congress to see which party exercises the most partisanship -- and the Democrats win the prize.
In fact, the Democrats take nine of the top ten partisan spots, as well as scoring 8 points higher in partisanship as a party. The lone Republican ties for first, though:
100% - Charlie Norwood (R-GA)
100% - Nancy Pelosi (D-CA)
99.7% - Nita Lowey (D-NY)
99.4% - Juanita Millender-McDonald (D-CA)
99.1% - Carolyn Maloney (D-NY)
98.9% - Xavier Bacerra (D-CA)
98.7% - Diana DeGetter (D-CO)
98.6% - Gary Ackerman (D-NY)
98.6% - Hilda Solis (D-CA)
98.6% - Ellen Tauscher (D-CA)
98.6% - Al Wynn (D-MD)
Of course, Norwood is dead, and has been since February (h/t: The Anchoress). After Norwood, the next Republican comes in at 94.8%. JoAnn Davis (R-VA) has only cast 134 votes, however, as she has missed significant time while fighting a recurrence of breast cancer. She comes in at #174 on the list of partisans -- which means that Democrats occupy all of the previous 173 slots, of those among the living, anyway.
In comparison, Republicans occupy all of the ten positions for the least partisan Representatives. The percentage of party votes for these range between 68%-78.4%. The first Democrat at that end of the spectrum comes in at #18.
If people want to know which party better puts bipartisanship into practice, and which holds the top living 173 slots for partisanship in Congress, the Post has the information for them. (via The Moderate Voice)
UPDATE: Hey, what do you know? The Democrats win in the Senate, too! The Republicans make it a little closer, being less partisan by only six percentage points this time (88.5%-82.3%), but the Democrats sweep the Top Ten Partisans again:
97.8% - Dick Durbin (D-IL)
97.1% - Ben Cardin (D-MD)
97.1% - Daniel Inouye (D-HI)
97.1% - Frank Lautenberg (D-NJ)
97.0% - Joe Biden (D-DE)
97.0% - Sherrod Brown (D-OH)
96.7% - Jack Reed (D-RI)
96.7% - Sheldon Whitehouse (D-RI)
96.6% - Hillary Clinton (D-NY)
96.6% - Chuck Schumer (D-NY)
The most partisan Republican in the Senate is the newly-seated John Barasso of Wyoming, at #13 on the list but with only 51 votes. Of Republicans who have served more than a few weeks, Johnny Isakson (R-GA) is tops ... at #28. Republicans take the top 14 spots of the most bipartisan Senators, with Lousiana's Mary Landrieu breaking the Democratic jinx.
Democrats -- They put the party in partisanship!
