TNR’s Michael Crowley asks why Obama isn’t pressing Hillary on her claims to have more “experience,” a questionable claim based largely on her time as First Lady:

So far this “experience” theme seems to be keeping Hillary in the lead over Barack Obama. But what does she really mean when she talks about “experience”? Given that Hillary has spent just over one (cautious) term in the Senate, she’s clearly talking about her time as First Lady (and to a lesser extent as First Lady of Arkansas). Yet Hillary actually says very little about the particulars of her White House years… Hillary almost never talks about sitting in on her husband’s key policy meetings, or otherwise shaping substantial components of his agenda…

Why not? Probably because right now Hillary gets to have it both ways: She enjoys this vague claim to “experience,” without getting bogged down in specific issues, because people only have foggy notions of her role as First Lady…

So here’s an idea for Barack Obama: Start pressing Hillary for some specifics about all this experience–particularly on issues that might rile up the party’s base…

But as I’ve pointed out before, directly questioning Hillary’s experience in the White House is an open invitation for Bill to weigh in much more strongly on her behalf. No one wants to do that in a Democratic primary.
