How bad is GOP obstructionism in the Senate? Republican senators are on pace to more than triple the previous record for uses of a filibuster in a Congress. In 2009, there were a record 112 cloture votes (the number of cloture votes is how you measure the use of filibusters). So far in 2010, there have already been more than 40 cloture votes. The previous record was in 1995-1996, when the Republican-controlled Senate required 50 cloture votes.
