By Harrison L. MichelsonArlen Specter rocked the political world when he announced he was switching parties and running as a Democrat in the 2010 election. The switch does give the Democrats a 59 seat majority in a 99 seat Senate, which is 59.5% of the seats. This does not give Democrats the ability to invoke cloture by all its members. Unless Norm Coleman is reelected from Minnesota, which seems unlikely, the Democrats will gain the 60 votes and the 60 percent necessary to invoke cloture.
Specter said, "I have traveled the State, talked to Republican leaders and office-holders and my supporters and I have carefully examined public opinion. It has become clear to me that the stimulus vote caused a schism which makes our differences irreconcilable. On this state of the record, I am unwilling to have my twenty-nine year Senate record judged by the Pennsylvania Republican primary electorate. I have not represented the Republican Party. I have represented the people of Pennsylvania."
