This is breaking news that just came in – Senator Arlen Specter (R-PA) is expected to announce that he will run in the Democratic primary in 2010. Specter had expected to face a tough primary if he stayed in the Republican Party.
This could be a good move for him, but if the Republicans get a strong candidate out, he’ll probably lose that seat. I’ll post again as soon as Specter releases a statement or has a press conference. Right now, I don’t have many details, but it appears as if he will stay in the Republican caucus until 2010.
