With key midterm elections approaching, the Republican Party is gaining more ground over Democrats according to a recent Gallup poll.

The weekly Gallup survey shows that the GOP leads 51 percent to 41 percent among registered voters.

The 10-point lead is the largest for Republicans this year and in Gallup's history of tracking the generic preference for Congress.

The latest survey is based upon a survey of registered voters conducted from Aug. 23 - 29.

The generic ballot poll is used as a predictor of the national vote for Congress. Gallup, one of America's oldest pollsters, has been tracking the generic preference since 1942.

Midterm elections will be held Nov. 2.
