Budget vote shows Specter's party switch isn't a lock

WASHINGTON -- Hours after telling President Obama that he would be no automatic vote for Democrats — even though he had just joined their ranks — Pennsylvania Sen. Arlen Specter proved the point.

In one of his first major votes since defecting to the Democratic Party, Specter sided with Republicans and voted against a $3.4 trillion budget Wednesday night that laid the broad groundwork for policies championed by Obama's administration.

Though not unexpected, the vote underscores Specter's independent streak. It also suggests that just because Democrats are one seat closer to a 60-vote majority, it doesn't mean Obama's agenda will be a lock in Congress.

As Congress prepares to tackle an overhaul of the nation's health care system and a proposal to reduce carbon dioxide emissions, it may be crucial for the Senate Democrats to reach 60 votes to overturn GOP-led filibusters that could block votes on bills.

Now with Specter as a Democrat, the party hopes to rely on 59 votes. They could hit 60 this year if Al Franken wins the Minnesota race. Franken is ahead, but the state's highest court is considering a challenge to the results.

Specter, a five-term senator known as a contrarian, appeared with Obama on Wednesday — a day after he announced he has switched parties and will seek re-election as a Democrat in 2010. He said he will help advance Democratic policies but also cautioned: "I will not be an automatic 60th vote."

Emory University political scientist Randall Strahan said it is a mistake to believe that Specter will help "produce a solid filibuster-proof majority in the Senate that will support all the initiatives of the administration."

"Sen. Specter has been a fairly independent senator as a Republican, and I don't think that's going to change," Strahan said.

Nevertheless, advocates of expanding health insurance coverage predict Specter will put Congress in a stronger position to pass a bill this year.

Specter, who has battled cancer, has sought increased funding for medical research in the past and was one of nine Senate Republicans who voted this year to expand state health insurance programs for children.

"I think his natural inclinations are to be supportive of meaningful health care reform," said Ron Pollack, executive director of Families USA, which has advocated health care legislation. "Now, he can vote his more natural inclinations."

Specter also has sponsored legislation to reduce emissions, though the bill relied on less aggressive deadlines than a proposal under consideration in the House. Daniel Lashof, director of the Climate Center at the Natural Resources Defense Council, said he expects Specter can help the Senate pass a climate-change bill.

"President Obama, whose leadership is going to be critical, now has a lot of leverage with Sen. Specter," he said.

Specter opposed Republicans on 38% of his votes in 2008 and 51% in 2007, according to a Congressional Quarterly analysis. In February, he was one of only three Republicans to back Obama's $787 billion stimulus plan.

Democrats, including Senate Majority Leader Harry Reid, have said they did not ask Specter to commit on the main issues facing Congress this year.

"Of course, it moves us one vote closer on critical votes," said Senate Majority Whip Dick Durbin, D-Ill. "I wouldn't presume to guess what his vote would be on any given issue, but I'm hopeful that he'll be supportive of President Obama's agenda."

Sen. Robert Casey, D-Pa., said Specter will have the freedom to take more moderate positions on controversial issues because he will no longer have to answer to the conservative wing of the Republican Party. Specter faced a primary challenge from Pat Toomey, former director of the conservative Club for Growth.

"I do think it overall moves the president's agenda," Casey said. "I think it would have been increasingly harder for him to work on the broader agenda."

Sen. Judd Gregg, R-N.H., who considered joining Obama's Cabinet but then backed out, agreed. "When you join a caucus," he said, "you have to vote with them most of the time."
