Could CNN's electoral map shift Wednesday? Check back at 4 pm for the answer.

(CNN) – Will the Democrats get Rocky Mountain high in Colorado?

The answer could determine who wins the race for the White House.

It's no coincidence Democrats decided to hold last month's presidential nominating convention in Denver. Colorado hasn't voted for the Democrats in a presidential election since 1992. But President Bush won the state by only 5 points over Senator John Kerry in 2004, the Democrats made major gains at the state level in the past two elections — and in this presidential election, the Obama campaign hopes to turn the state from red to blue.

The poll will also include new state surveys on the battle for the presidency in Montana, Michigan, Pennsylvania and West Virginia.

Sen. Obama campaigned in Billings, Montana last week.

(CNN) – Sen. Barack Obama appears to be headed for a win in one of the final contests of the Democratic nomination race, according to a new poll of likely Democratic primary voters in Montana.

Obama’s support stands at 52 percent and Clinton’s is at 35 percent. Thirteen percent of those who participated in the survey were unsure who they preferred as the Democratic nominee.

Montana and South Dakota will hold the last Democratic presidential primaries on June 3; sixteen pledged delegates are up for grabs in Montana’s primary and 15 in South Dakota.

(CNN) — Barack Obama's campaign circulated a report Tuesday that accused the Clinton campaign of misleading reporters about the motivation of a new Clinton backer.

The headline on the Clinton campaign's Monday press release — "Yellowstone County Commissioner Bill Kennedy Backs Hillary Clinton for President: Prominent Montana leader cites Obama's out-of-touch comments about rural America" — seemed to imply that the official had made the switch because of Obama's recent remarks.

But lower down in the press release, the official says Obama's comments had only "solidified his support" for Clinton, not sparked his decision. A news story circulated by the Clinton campaign a short time later used much of the same language contained in the original press release, and led some to conclude that Kennedy's endorsement had been sparked by the controversy over Obama's 'bitter' remark.

Asked Monday afternoon, shortly after the second release was sent, whether the potential discrepancy raised by the headline could be misleading, a Clinton spokesman told CNN that the original memo was accurate — in sending the second e-mail, he said, the campaign was merely "passing along" relevant published information.
