Yesterday was, it turns out, a good day: so far, 18 senators previously in favour of PIPA now oppose it, seven of whom were former co-sponsors of the act.
We already told you about the fact that Marco Rubio and a handful of other senators had changed their minds, but the list has gotten much longer.
It means that neither side is close to having a majority on the act. According to a whip count by OpenCongress, there are currently 35 supporters (including 34 co-sponsors), 18 opponents and 12 more senators leaning toward opposition. Interestingly, about 35 senators have not committed to a position. Good fence-sitting, guys.
We'll keep this list up-to-date, but at the time of writing, the full list of new opponents reads (a "*" indicates that the senator was originally a co-sponsor):
Roy Blunt (R-MO) * John Boozman (R-AR) * Scott Brown (R-MA) Ben Cardin (D-MD) * John Cornyn (R-TX) Jim DeMint (R-SC) Orrin Hatch (R-UT) * James Inhofe (R-OK) Mark Kirk (R-IL) Jeff Merkley (D-OR) Lisa Murkowski (R-AK) Marco Rubio (R-FL) * Olympia Snowe (R-ME) David Vitter (R-LA)* Tom Coburn (R-OK) Pat Toomey (R-PA) Mike Johanns (R-NE) Kelly Ayotte (R-NH)*
