(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.

The Mason-Dixon poll of 400 likely Democratic primary voters in Montana was conducted May 19-21 and has a margin of error of plus or minus five percentage points.

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.
