Another postscript: How Idaho legislative seats have shifted with a White House incumbent topping the ticket

In Friday morning’s column I chewed on whether Democrats might overcome President Obama's unpopularity and gain seats in the Legislature this year.

I didn't have room to share what I learned by reviewing every presidential race since statehood. I couldn't have done this without Idaho Secretary of State Ben Ysursa's invaluable Blue Book, edited by Pat Herman.

There have been 23 contests with an incumbent president or vice president on the ballot since 1890. Partisan data doesn't exist for the 1892 legislative election, but the Blue Book provides the rest.

In short, Idaho Republicans gained in 13 of the 22 elections.

In the 13 elections when incumbent Republicans topped the presidential ticket, Idaho Republicans made net gains in nine of those years, with Democrats doing better four times.

In the 10 elections when incumbent Democrats were at the top, Democrats added seats five times and retreated five times.

After reading the column, Boise State political scientist emeritus Jim Weatherby said he found a pattern: Idaho Democrats can pick up legislative seats when they have a strong candidate at the top.

In four of the five cases where Idaho Democrats gained seats, the presidents were Woodrow Wilson, Franklin Roosevelt (twice) and Harry Truman, all Democratic wins. The one exception was Democratic Vice President Hubert Humphrey, who lost to Republican Richard Nixon in 1968. But the Democrats' legislative gain was just two seats in that historically wrenching year, the lowest shift of any of the 22.

This year is not likely to have most Idahoans considering Obama in the same league with Wilson, FDR and Truman. “Both (Bill) Clinton and Obama have or are as unpopular in Idaho as most anywhere else,” notes Weatherby.

Here’s the dope:

Democrats Are a Non-issue

Ever since the hard left radicals took over the Democrat party they have become less and less influential in Idaho. That is because Idahoans are essentially a conservative or maybe even a Libertarian bunch. The Democrat party has taken off on a tangent Idahoans reject. We do not want an ever increasingly powerful government telling us what to do. Decades ago when Democrats represented the working man, Idahoans, in particular the north Idaho miners and saw mill workers, supported them. But since the EPA came to power and Idaho rejected forced unionization coupled with the socialist oriented Democrat national organization, they have all but disappeared. And a good thing it is. Maybe someday the Democrat party members will disavow socialism and get back to what made the party relevant. I doubt they will but who knows?

If you can't nuculer Democratic, don't hyphenate a bullfrog

If we are the "Democrat" Party the you can build your own towers.
