Oklahoma was won by Republican nominee John McCain with a 31.3% margin of victory.

A strongly conservative state located in the Bible Belt where evangelical Christianity plays a large role, Oklahoma has trended heavily Republican in recent years.

Here are their last predictions before election day: McCain won every single pre-election poll, and each with a double-digit margin of victory.

[18] Oklahoma gave John McCain his strongest showing in Election 2008 with a rounded percentage of 66% (65.65%) going to him.

Although the results were similar to 2004 in which George W. Bush swept every county in the state with 65.57% of the vote, McCain's margin of victory was slightly better - 0.08% more - in 2008.

[20] Oklahoma was one of five states where McCain outperformed George W. Bush, the other four being Arkansas, Louisiana, Tennessee, and West Virginia.

McCain's selection of the socially conservative Governor Sarah Palin of Alaska proved to be an excellent fit for Oklahoma.

Despite the Republican landslide, Obama did improve upon John Kerry's performance in Oklahoma City and Tulsa.

However, this was more than canceled out by his extremely weak showing in Southeast Oklahoma, historically the most Democratic region in the state.

Democratic nominees from John Kerry on, on the other hand, have proven spectacularly bad fits for the region and the state as a whole.

All 7 were pledged to John McCain and Sarah Palin:[22] The slate for the Democrats, which was not elected, consisted of Sally Freeman Frasier, Gene A. Wallace, Anita R. Norman, Tim Mauldin, Robert Lemon, David Walters, Walter W. Jenny Jr.[23]
