The newly-opposed Senators are skewed strongly to the Republican side of the aisle. An Ars Technica survey of Senators' positions on PIPA turned up only two Democrats, Ben Cardin (D-MD) and Jeff Merkley (D-OR), who announced their opposition on Wednesday. The other 11 Senators who announced their opposition on Wednesday were all Republicans. These 13 join a handful of others, including Jerry Moran (R-KS), Rand Paul (R-KY), Mark Warner (D-VA), and Ron Wyden (D-OR), who have already announced their opposition.
Marco Rubio, a freshman Republican Senator from Florida who some consider to be a rising star, withdrew his sponsorship of the bill, citing "legitimate concerns about the impact the bill could have on access to the Internet and about a potentially unreasonable expansion of the federal government's power to impact the Internet." He urged the Senate to "avoid rushing through a bill that could have many unintended consequences."

The partisan slant of the defections is surprising because copyright has not traditionally been considered a partisan issue. Before Wednesday's protests, PIPA had 16 Republican co-sponsors and 23 Democratic ones. The bill lost a quarter of its Republican sponsors on Wednesday, while we know of only one Democrat, Ben Cardin (D-MD), who dropped his support.
Those who dropped their support were most likely bolstered by strong opposition from conservative think tanks and blogs. On Tuesday, the influential Heritage Foundation announced that it would include SOPA and PIPA as a key issue on its voter scorecard. And the popular conservative blog redstate.com, whose founder threatened to mount primary challengers to SOPA supporters last month, has been hailing Senators who come out in opposition.
