More than $132.5 million has been spent on TV ads for gubernatorial races, USA Today's Fredreka Schouten and Erin Kelly report, which is almost twice as much as what was spent during the same period in 2014.

Why it matters: Most of the midterms focus has been on the House, but gubernatorial races from Colorado to Maine are quickly becoming more competitive, forcing spending to reach new levels.
