Will it be Specter or Sestak?
It's now less than a week before the primary and THREE separate polls say Sen. Arlen Specter and Rep. Joe Sestak are in a dead heat going into this final leg of the race.
Rep. Joe Sestak on Tuesday announced he would challenge Republican-turned-Democrat Sen. Arlen Specter, setting the stage for a Pennsylvania primary race likely to center on Specter's Democratic credentials.
