This is huge. Arlen Specter (Republican-Pennsylvania) has announced that he will be joining the Democratic Party. There appears to be little or no room for moderate Republicans in the Republican Party.

From WaPo:

Pennsylvania Sen. Arlen Specter will switch his party affiliation from Republican to Democrat and announced today that he will run in 2010 as a Democrat, according to a statement he released this morning.

Specter’s decision would give Democrats a 60 seat filibuster proof majority in the Senate assuming Democrat Al Franken is eventually sworn in as the next senator from Minnesota. (Former senator Norm Coleman is appealing Franken’s victory in the state Supreme Court.)

“I have decided to run for re-election in 2010 in the Democratic primary,” said Specter in a statement. “I am ready, willing and anxious to take on all comers and have my candidacy for re-election determined in a general election.”

He added: “Since my election in 1980, as part of the Reagan Big Tent, the Republican Party has moved far to the right. Last year, more than 200,000 Republicans in Pennsylvania changed their registration to become Democrats. I now find my political philosophy more in line with Democrats than Republicans.”

President Obama was informed of Specter’s decision at around 10:25 a.m., according to White House officials, and reached out to the senator minutes later to tell him “you have my full support,” and we are “thrilled to have you.” (more…)

As usual, Steve has the correct perspective:

… talk of a “filibuster-proof” Democratic majority is a stretch. For one thing, Norm Coleman just received a powerful reminder incentive to keep his legal fight going for as long as humanly possible. For another, the Democratic caucus, even at 60, still has Ben Nelson and Evan Bayh to consider.

But if reaching the 60-vote threshold doesn’t make Arlen Specter’s big switch “huge,” what makes today’s news a seismic political shift? It’s further evidence of a Republican Party in steep decline, driven by a misguided ideological rigidity. Indeed, Specter suggested as much in his statement: “Since my election in 1980, as part of the Reagan Big Tent, the Republican Party has moved far to the right.”

Steve wraps up this post with:

Indeed, it sends a signal to voters: the Republican Party is home to Limbaugh, Tea Baggers, Palin, right-wing blogs, the Rove/Cheney/Gingrich triumvirate — and no one else. The party that’s been shrinking to generational lows just got even smaller.

For three months, the conservative message has been that President Obama, his widespread popularity notwithstanding, is some kind of radical ideologue, far from the American mainstream. Specter’s departure from the GOP sends the exact opposite message. Moderate Republicans are teaming up with Obama, and leaving the party that has “moved far to the right” behind.

I couldn’t agree more. Just sit down and watch Fox News. Look at the issues that they are talking about: Obama shaking hands with Chavez and whether Obama is appeasing our enemies. These are amazingly tone deaf non-issues. Americans are hurting and the Democratic Party is at least attempting to address the problems that concern Americans.
