Montana Primary: What To Expect Tonight

Tonight marks the end of the democratic primary season. The last two states to vote are Montana and South Dakota. Below is a list of what to look out for in Montana during tonight's season finale:

Montana: Obama expected to win, but the margin might be tighter than expected. Montana has 16 superdelegates up for grabs.

Here are five things the pros will be watching in Montana (from The Politico - get the full take here):

East vs. West:
Though Obama led Clinton 52 to 35 percent (with 13 percent undecided) among likely Democratic voters in Montana in a Mason-Dixon poll conducted May 19-21, his margin came almost entirely from the western part of the state.

The Battle for Billings:
About 15 percent of the state's population live in Billings, Montana's largest city with about 100,000 residents, and surrounding Yellowstone County.

The Tribal Vote:
Montana's seven Indian reservations are home to only about 8 percent of the population, but typically produce 20 percent of the vote in Democratic primaries... Still, the Clinton campaign is concerned about the Indian vote. That's because they believe Indian country may be reluctant to accept a female president and Obama's "Hope" rhetoric could play well in its economically distressed communities.

The Student Vote:
The Obama team has asserted that the student vote - a major source of their support - has been on the decline somewhat in the contests held in and after May, when most universities let out for the summer.

Rush Limbaugh vs. Obamacans:
Montana, which doesn't have party registration, opens its primaries to all voters, and both campaigns will be keeping an eye on high percentages of Democratic primary votes coming out of Republican counties.
