Six weeks before the Democratic Senate primary, Senator Arlen Specter holds a solid lead over challenger Joe Sestak.
That's according to the latest Quinnipiac University poll, which surveyed likely primary voters.
Assistant polling director Peter Brown says Congressman Sestak has a big challenge ahead of him, if he wants to make the race more competitive.
"The simple math tells you that if, since Mr. Specter's at 53 percent, if Sestak won every undecided vote, he could still only get to 47, under this poll. It's a tough climb for Mr. Sestak. It's not an impossible climb."
In the poll of likely primary voters, Sestak received 32% support.
