Do you seriously expect more to join the frey?
I’ve heard rumblings but no names yet.
I think this is an election cycle that anything can happen. Congress is at an all time low on approval rating, no one really like BHO...people are finally getting educated about progressives, etc...
I think a dark horse could enter the race late and really turn things upside down.
I think establishment players that are up for re-election face a daunting task of getting back in this election.
