According to CNN's analysis of several recent polls from both states, Clinton holds a 30-point lead in Kentucky while Obama is up by 10 in Oregon.
In Kentucky, Clinton is winning 58 percent of the vote while Obama is at 28 percent. Kentucky has a broad swath of working class white voters - the demographic that has long supported Clinton and propelled her to a 41-point victory in West Virginia one week ago. Her large margin in Kentucky appears to indicate those voters are sticking with Clinton, even as Obama appears to be the presumptive Democratic nominee.
In Oregon, Obama is winning 50 percent of likely Democratic voters there while Clinton is at 40 percent. With a large population of young voters and those who are college-educated, that state has demographics that have long favored Obama's candidacy.
Oregon is conducting a vote-by-mail primary, which means that a large number of voters in that state have already cast their ballots.
In Kentucky, 51 delegates are at stake while 52 are up for grabs in Oregon. It remains impossible for Clinton to catch Obama in pledged delegates, but the New York senator is looking to catch Obama in the popular vote total.
