The National Republican Senatorial Committee has launched a new Web site -- Meet Democrat Arlen Specter -- to help Pennsylvania Democratic voters get to know their new U.S. senator.

Arlen Specter has a long history with the Republican Party and has represented Pennsylvania in the U.S. Senate since 1981 as a Republican. Specter's days with the GOP ended Tuesday when he announced he is switching his party registration to Democrat and would seek re-election in 2010 as a Democrat.

While Specter has attracted substantial support among moderate Pennsylvania Democrats, will the liberal base of the Democratic Party support Specter in 2010 as he seeks the Democratic Party nomination to run for another six-year term in the Senate?

Potential Democratic voters may want to view the YouTube clip of George W. Bush endorsing Arlen Specter in 2004. There's also a clip of former Pennsylvania Sen. Rick Santorum endorsing Specter.

The Web site includes postings such as "Specter Opposing Democrats And Their Priorities" and "Specter Supported Republican Policies That Democrats Opposed" and one of Specter praising Rush Limbaugh.

It's all designed to give hard-core Democrats second thoughts about supporting a political opportunist like Specter.

(If you're Rep. Joe Sestak or Joe Torsella -- two Democrats considering running against Specter next year -- you can thank the GOP for digging up all this dirt on Specter for you.)
