Today's two presidential primaries are not expected to provide many fireworks. Clinton is heavily favored in KY, as is Obama in OR (though her percentage margin in the former is likely to significantly exceed his in the latter). OR's all-mail-in-ballot system will get some television attention. Because OR requires mailed ballots to be received by election day, its system won't delay the count as is often the case in neighboring WA. But it certainly makes exit polling more of a challenge (presumably, the phone interviews of voters that will be used as the functional equivalent of exit polls will be done by pretty early today).

There were rumors last week that Obama would all but claim victory in his primary night event in IA, on grounds that he would have clearly won a majority of pledged delegates. But as part of his continuing effort to let HRC exit the race gracefully, he's made it clear there will be no official victory claims tonight. Meanwhile, HRC is sticking to her argument that the pledged and overall delegate targets must be adjusted to include MI and FL, a measure by which Obama still has a ways to go. Meanwhile, Clinton is already claiming a popular vote lead, based on a measurement that includes FL and MI and excludes four caucus states where raw votes have not been reported. We'll hear more about that from her tonight. But don't expect any dramatics.
