BOISE- It's been just two months since Idahoans cast their votes for their top presidential picks, and that could really put a damper on voter turnout for Tuesday's primary election.

"This is a very strange primary election year in that this is the second primary," said KTVB political analyst Dr. Jim Weatherby. "I'm concerned some people think they've already voted in the primary and have some confusion between the two."

Weatherby says in addition to that impacting numbers at the polls, so could the fact that there aren't any top of the ticket attention grabbers like we had two years ago.

"There were really strong contested races for governor, secretary of state, attorney general, superintendent of public instruction and second congressional district.," said Weatherby.

Although there many not be any real contentious races this time around, Weatherby says the most important statewide race is for the spot on the Idaho's highest court. Four people are running to replace Justice Jim Jones who is not seeking re-election.

It's a race that voters have to really do their research on because it's nonpartisan.

"Often voters have cues on who is the Democrat and who is the Republican, but these are relatively unknown people," said Weatherby. "I think it's hard for the voters to make a decision in a race like that."

Weatherby says with the other races electing people, by far the most activity is on the Republican side, and with all the in-party fighting going on, there could be some surprises.

"We do over the years talk about incumbent advantage," said Weatherby. "I don't know if that's so much an advantage this year when there is this anti-establishment, anti-experience mood in the country. We'll see how strong that is in Idaho."
