Joe Sestak is on MSNBC. He's not ruling out running.

[Thrill]

Thats great to hear. Reid you don't get to decide who we run!!!!

I found it interesting Joe Sestak said he's going to be watching him

[librechik]

1. I love Sestak--the least he will do is move Arlen to the Left!

Or maYbe even get the waffler out altogether.

Tuff choice.

2. Sestak won't run

He couldn't beat Specter

[Bunny]

8. Yep. There are currently no PA Dems who could beat Specter. None.

This is a slam dunk for Arlen.

[LynneSin]

9. I'm thinking Sestak is the 'warning shot' for Specter....

As long as Specter keeps his end of the deal then Pa Dems will keep theirs and not run someone. Sestak's 'wait & see' is the PA Dems saying we will run someone if you dick us over.

3. Yay! The more Arlen Watchdogs

the better:bounce:

[SpartanDem]

4. I support his switch,but this isn't bad

it'll keep Arlen on his toes.

5. good

he shouldnt rule it out.

last time i checked, people are free to run for whatever office they want to run for.

i know he'll have my support.

6. I don't think it's a credible threat, but politicians tend to take uncredible threats seriously

Sestak could definitely keep Specter on his toes.

[LynneSin]

10. That's exactly what Sestak and the PA Dems are doing

Perhaps Sestak is promised Specter's seat if it becomes available fore 2016.

7. Now that's what I call checked and balanced!
