1. Presumably, the way will be cleared for Specter in the Democratic primary. But how thoroughly and quickly. And will there still be a Democratic challenger in the primary, even if the party establishment wants to clear the way.
2. What if anything was promised to Specter to make the switch? I suspect he didn’t need to be promised that much, because he could see he couldn’t make it through the Republican primary. But what happens with his seniority in the Senate, stuff like that?
