Economy main issue for voters, poll finds

"It is clear the economic concerns are paramount in voters' minds with the midterm elections less than two months away," states Gallup. "A poor economy makes reelection challenging for incumbents, especially those from the governing party."

Gallup's tracking of the 2010 election shows voters preferring Republicans to Democrats.

"However, the extent to which voters' concerns center more around the specific issue of jobs and less around the economy more generally could provide an opportunity for Democrats to improve their party's standing this fall."
