He can go, any time

Rico says Arlen Specter is an old, staunch, and stupid Republican, and will hopefully get beaten like a rented mule by Chris Matthews (or whoever runs against Specter) in the next election in 2010:

The GOP moderate said he expected challenges from the left and right as he seeks a sixth term. "I'll be prepared, whoever my opponents are," Specter said on CNN's Late Edition. "Feeling good," quipped the Republican, who has survived bouts with a brain tumor and cancer while serving in the Senate. "Top of my game."
