Partisan Democrats had a lot to be happy about last night's vice presidential debate. Vice President Joe Biden turned in an aggressive and energetic performance that they wished they'd seen in President Obama.
And while Republicans have cried foul on Biden's behavior (GOP surrogates called him "rude"), they argue that Rep. Paul Ryan's calm, unflustered demeanor and his solid performance on foreign affairs was appealing to swing voters, especially women.
Could they both be right? Sure. Democrats could get a spring back in their step, while swing voters also remain interested in hearing more from Romney/Ryan ticket.
Which, of course, makes the presidential debate next Tuesday all that more important.
