I asked Sestak what those issues were beyond EFCA, and he proceeded to list just about every major item on the Democratic agenda: Economic security for Pennsylvanians--Specter voted for the Bush tax cuts; health reform--which Specter helped derail in the 1990s; education--reducing costs, and increasing quality so that Pennsylvania doesn't compete with Florida for the honor of being the oldest state in the union; the environment; and national defense--Specter voted, of course, for the Iraq war.
But according to Sestak, even if Specter moves in the right direction, the more important question is whether or not he'll actually stick to those new positions going forward. If Specter's re-elected, he'll be senator (potentially) until 2016, and Sestak worries he won't be reliable over time.
Interestingly, though, there may not be much daylight between Specter and Sestak on at least one of these issues. Sestak says he's still unsure whether he supports a public health insurance option as an element of comprehensive health reform. He plans to discuss the issue further with SEIU president Andy Stern and others and come to a decision in the coming weeks, but if he ultimately comes down against that policy, he'll be in just about the same camp as his new rival, who came out against a public option over the weekend. Obviously that means less in the House (where Sestak serves) than it does in the Senate (where Specter potentially wields enormous influence), but no less a figure than Howard Dean has said that comprehensive health reform requires a public option.
Last night, Stern told ABC news that "[i]t is hard to imagine any union supporting a candidate in the Democratic Party for the US Senate who doesn't have strong positions on both healthcare and Employee Free Choice," and this morning he sent out the message "Sestak is serious about Senate race" on Twitter.
