A pair of polls out today from Suffolk University are worth mentioning:
Clinton leads 51-26 in Kentucky -- another blowout, as expected, like West Virginia.
The surprise: The poll has Obama only leading 45-41, within the poll's margin of error of 4 points.
That's tighter than most polls -- the average of Oregon polls in May has been Obama up 11. But the last two, by ARG and Suffolk, have had him up 5 and 4.
What if she upsets him in Oregon? Then, will the press still be able to write her off? And, what if she blows him out in Kentucky and he wins narrowly in Oregon? Then, her scenario of winning the popular vote with another blowout in Puerto Rico actually begins to register on the radar.
He is expecting to secure a majority of pledged delegates on Tuesday, and harvest a lot of additional superdelegate endorsements as a result. But if she draws realistically closer in the popular vote, the harvest could be limited.
