Washington (CNN) - It's often overshadowed by the battle for control of Congress, but the Democratic and Republican parties are ramping up their efforts in the crucial fight for control of the nation's governorships.
The Republican Governor's Association announced that they launched new commercials in Ohio, Wisconsin, Oklahoma, Maine and Michigan Wednesday and Thursday. The governorships in all five states are currently held by Democrats. And the RGA confirms that it's also donating $500,000 to Susana Martinez, the GOP gubernatorial nominee in New Mexico - another state where the Democrats are fighting to hold onto a governors' office.
Meanwhile the Democratic Governors Association is up with a new ad taking on Martinez, the Dona Ana County district attorney. The DGA is also running a new commercial in Ohio, as well as in Vermont and Maine.
While the battle for control of Congress dominates the headlines, the fight for the governorships is extremely important. Next year governors will have a big say in how the new Census numbers are used to alter congressional districts in their states.
Voters in 37 states cast ballots for governor this November.
