Both Hillary Clinton and Barack Obama visited Casper during the 2008 Democratic primary. But in heavily Republican Wyoming, the state’s Democrats are receiving unprecedented attention from the Clinton and Sanders campaigns, said Aimee Van Cleave, executive director of the Wyoming Democratic Party.

In Wyoming, Clinton has 11 staffers. Sanders has four full-time staffers and two full-time volunteers traveling with them.

“An incredible amount of resources are being spent on Wyoming’s delegates,” Van Cleave said.

Wyoming will send 18 delegates to the Democratic National Convention in Philadelphia in July. Fourteen of those are up for grabs. Four are superdelegates who have committed to Clinton, Van Cleave said.

The process of selecting delegates in Wyoming begins April 9, at county Democratic conventions. Delegates chosen at those conventions will attend the Wyoming State Democratic Convention in May in Cheyenne, where the national delegates will be selected.

But the proportion of candidates selected to go to the national convention for each candidate is based on the proportion of delegates they win at the county conventions on April 9, Van Cleave said.
