People wondering why the White House does tough, public pushback against Howard Dean but not against the likes of Ben Nelson or Joe Lieberman ought to take a deep breath and consider that Nelson and Lieberman . . . get votes in the United States Senate.

The White House hasn’t publicly attacked Bernie Sanders or Roland Burris over there Dean-esque doubts any more than they’ve publicly denounced Nelson or Lieberman. That’s because the White House doesn’t want to get into a downward spiral of recriminations with any of the 62 Senators who they’re hoping will vote for the bill.
