Put this into the "unsurprising" category. Former Rep. Pat Toomey (R-Pa.) welcomed Rep. Joe Sestak (D-Pa.) to the next year's Pennsylvania Senate race Wednesday evening.

Sestak appear to say he intends to challenge Sen. Arlen Specter (Pa.) in next year's Democratic primary on MSNBC Wednesday.

In a statement, Toomey praised Sestak for being a "principled liberal."

"While Joe Sestak and I disagree on a host of issues, I commend him for being a principled liberal who stands up for his beliefs and values," Toomey said. "I have always believed that Pennsylvania voters - not party bosses in Washington - should have the final say over whom their nominees will be."
