It was a clean sweep for Mitt Romney tonight as he nailed the Oregon primary shortly after he was declared the winner in Nebraska. The Nebraska win was a "beauty contest"— the state's 32 delegates will be decided at the Nebraska convention in July. But most if not all of Oregon's delegates will go to Romney. Mitt grabbed 73% of the vote, followed by Ron Paul with 12%, Rick Santorum at 9% and New Gingrich with 5.6%, according to Politico. Romney has all but clinched the GOP nomination, and is cruising toward winning the 1,144 delegates he needs, reports AP. (More Oregon stories.)
