On the night that Barack Obama clinched his party’s nomination, one-third of Hillary Clinton’s supporters in Montana and South Dakota said they would not vote for the presumptive Democratic nominee.
Exit polls from both states demonstrate that Obama inherits a fractured coalition after the longest primary race in modern history. Demographic divisions dug by class, race, gender and political philosophy haunted Obama until his last contests, effectively forcing the Illinois senator to limp across the finish line Tuesday night.
The cappuccino versus coffee Democratic divide between upper class and working voters continued. Coffee Democrats were more likely to back Clinton while cappuccino Democrats were more likely to back Obama. That these divisions were also deepened by gender and racial identity — rooted in long-sought historic firsts for women and blacks — means that there exists an unprecedented intra-party burden that befalls Obama.
On Tuesday the more working-class white Democratic electorate of South Dakota once again proved un-winnable for Obama, as has been the case in contests from Ohio to Kentucky. By contrast, Obama won Montana, which was more upper class than South Dakota, and not nearly as liberal as in Oregon and Vermont, where Obama has fared best.
In Montana, Obama won six in 10 Democratic voters who had completed college but only won half of those without a college degree. In South Dakota, Clinton won six in 10 working class voters, while earning a slimmer majority of support from college-educated voters.
Four in 10 South Dakota voters were college educated, compared to half of Montanans.
Slightly more voters were liberal in Montana than South Dakota. Democratic voters in South Dakota were also about 10 percentage points more likely than in Montana to name the economy as their most important issue.
Roughly one quarter of Clinton voters in Montana said they would vote for McCain in November if Obama were the Democratic nominee; about one in 10 said they intended not to vote. When South Dakota Democratic voters were asked how they would vote if Obama was the Democratic nominee, about 15 percent of Clinton supporters said they would back McCain and an equal portion said they intended to sit out the general election.
