Well, Oklahoma and Utah don't. Oklahoma's Legislature will be 68 percent Republican next year, while Utah's will be 77 percent Republican. Idaho's will be 81 percent Republican.
But here's a stat:
Oklahoma's U.S. House delegation was the second-most conservative in the nation, according to 2009 rankings by the National Journal, a news magazine that covers Congress and politics, beating both Idaho and Utah. And Oklahoma's two senators were the most conservative combo.
Wyoming's red ratio
Which House delegation was more conservative than
Wyoming's, but it's only one person.
Wyoming also has the highest percentage of people who identify themselves as conservative, according to a Gallup poll released in August. Oklahoma finished ninth in that poll, behind Utah and Idaho.
All of Wyoming's members of Congress and statewide officers are Republican, and its Legislature is 84 percent Republican, higher even than Idaho.
But, Oklahoma beat Wyoming in 2008 in the percentage of votes for Sen. John McCain, the Republican presidential nominee — 65.6 to 65.2.
"Wyoming was always Republican," said University of Oklahoma professor Keith Gaddie. "Oklahomans have made this conscious choice to overthrow Democrats."
'A question of when'
Gaddie, who is writing a book for the OU Press called "Red State Rising," said no Democrat even came close to winning statewide office last week.
"It was going to happen someday," he said. "It was just a question of when. And now it's here."
Cole, who helped build and modernize the Oklahoma Republican Party as party chairman and a political consultant, said Democrats are weaker today as a party than Republicans were when Cole took over as chairman in 1985. Then, almost all of the congressional seats and statewide offices were held by Democrats, who also controlled both houses of the Legislature.
In the last two decades, Cole said, ideology has aligned with party.
"Oklahoma's a very conservative state," he said. "It's not a Republican state."
Like many, Todd Goodman, chairman of the Oklahoma Democratic Party, attributed Tuesday's results to the national wave that grew out of resentment toward Washington.
But he told supporters in an e-mail last week that "when the people of Oklahoma see what it is like to live in a state with total Republican control, the pendulum will begin to swing back our way."
