BOISE, Idaho (AP) — The head of Idaho's Democratic Party is criticizing the purchase of 22 state-funded billboards that advertise the state's upcoming presidential primary, but fail to include information that the March 8 election is solely for the Republican and Constitution parties.

Democratic Chairman Bert Marley called the billboards misleading and confusing in a letter sent to Republican Secretary of State Lawerence Denney. In a statement released Wednesday, Marley asked Denney to correct the alleged mistake by informing voters there is a statewide Democratic caucus on March 22.

However, Tim Hurst with the Secretary of State's office says they don't plan on informing voters of the statewide caucus because it's a party-sponsored event.
