His primary win does, however, reinforce opinion polls showing a majority of Utah Republicans and conservatives support Herbert's plan.
Support in political corners is also growing. On Thursday the Utah Association of Counties, a group representing the state's 29 county commissions, voted unanimously to support Herbert's plan.
"In the echo chamber of the Republican House, there's a belief that Republicans don't support the Medicaid expansion or Healthy Utah," said Nehring. "But in the real world, everything indicates this is something people do care about and want the Legislature to solve."
