28% of Hillary Fans Would Pick Mac Over Obama

In a troubling sign for Democratic odds of overcoming the primary bloodbath, a poll finds 28% of Hillary Clinton supporters say they would vote for John McCain over Barack Obama, and 19% of Barack boosters would go GOP over Clinton. It’s great news for the crossover-friendly Republican, the Chicago Tribune notes—and suggests Dem “divisions are running deep,” says the pollster.

The Gallup honcho did note it “may be normal” for voters to threaten to bail “if certain things do not happen to their liking.” Indeed, only 80% of Republicans said they’d vote McCain if his running mate isn't considerably to his right. But the poll still suggests that piecing together Democratic unity will be a major challenge for the nominee.
