WASHINGTON - New poll results released on Friday afternoon indicated that this year's US congressional race remains tight, with registered voters almost evenly divided between Democrats and Republicans.

The USA Today/Gallup poll, conducted between Sept 24 and 27, found 47 percent of registered voters prefer Democrats and 46 percent prefer Republicans.

Gallup said that the result essentially duplicates what it found in another poll in late August, showing Congressional vote choices have been close during the 2012 campaign, with neither party able to establish a consistent advantage.

One third of the US Senate will be on the ballot in this year's general election, while all of the House members are up for election.
