Though Barack Obama has now clinched a majority of pledged delegates, his bid for the Democratic nomination remains shaky to bloggers.

His insurmountable pledged delegate lead, gained Tuesday after his Oregon win and Kentucky loss, should prompt superdelegates to finally move his way, writes Jonathan Singer at MyDD. But his Kentucky drubbing — he won only 30 percent of the vote while Hillary Clinton netted 65 percent – should have Democratic strategists concerned with his inability to win working-class whites and rural voters, writes Chris Cillizza. Obama could have appeared more presidential if he made more of an effort to reach out to Kentucky voters, according to Josh Marshall. And it's unprecedented in primary history that a candidate becomes weaker as his nomination becomes inevitable, The Corner Mark Steyn adds.

Clinton seems far from giving up. Her campaign chairman, Terry McAuliffe, now claims she's ahead in the popular vote, which is only possible by including Florida and Michigan results and excluding four caucus states, Marshall notes. She's poised to become the Al Gore of 2008 by winning the popular vote but losing the contest, a result that caused problems for George W. Bush in 2000 and should worry Democrats, Byron York writes.

Obama may soon have to worry more about Sen. Joe Lieberman (I-Conn.), who has questioned why Obama and other Democrats have turned away from the interventionist foreign policies of Democratic Presidents John Kennedy and Franklin Roosevelt, writes Power Line's Paul Mirengoff, who wants Lieberman to speak on behalf of John McCain at the GOP convention. Lieberman is fast becoming more like former Sen. Zell Miller (D-Ga.) by converting from a Democrat with weak partisan ties to being someone who's "essentially a partisan Republican" who attacks his former party, writes Jonathan Chait at The Plank.

Congress, meanwhile, continues to load up on the pork, notes RedState's Pejman Yousefzadeh. Democrats have included $50 million more for military benefits to the war supplemental than President Bush has called for, and Republicans are going right along, Yousefzadeh writes.
