What the data clearly shows is that he GOP is filibustering at twice the rate of what the Democrats did before, including what they did under Bush. So Republicans can't claim that Democrats did it too - they didn't. Not like this.
Another interesting data point: IN the last ninety years, there have been 1,195 cloture motions filed, and a874 cloture votes, per the Senate site. The Republicans in the last three years that they've been in the minority, have caused 215 of the motions to be filed, and 157 of those cloture votes. That means in just the past three years, the Republicans have been responsible for 18% of all filibusters recorded in the past 90 years.
This was as of March 2, 2010!
