Mia Love came within a whisker of beating Matheson last year, and she has a better chance than anyone else of beating him next year. And after that, the sky’s the limit—she might replace Orrin Hatch in the Senate after 2018, or maybe run for governor someday.
This is Utah. I cannot imagine what Obama could do that could possibly make the electorate there hate him more. So off year election isn't an advantage for her. She had every advantage possible and she lost. If she was incapable of beating him last year then what makes you think she'll beat him next year?
