Here's another sign that the Obama campaign is dialing back the calls for Hillary to leave the race: On a conference call with reporters just now, Minnesota Senator Amy Klobuchar, who has now endorsed Obama, firmly asserted that Hillary has "every right" to stay in the race.

"I believe that Senator Clinton has every right to continue her campaign," Klobuchar said, adding: "I don't agree with those who have said things to the contrary."

Klobuchar also broke with the claim, voiced by many Dems of late, that a drawn-out contest could harm the party, asserting that she had no doubt that the two leading Democrats would do the right thing for Dems overall.

This of course could be more a reflection of Klobuchar's stated respect for Hillary than of her actual views on whether the race should continue. But Obama himself said over the weekend that Hillary should not drop out, and one wonders whether we'll now see a drop-off in calls for her to exit.
