Less than 20 percent of voters believe most members of Congress deserve reelection, on track for the lowest mark in at least two decades, a new poll says.

According to a Gallup poll released Monday, 19 percent of registered voters say a majority of lawmakers deserve to be reelected, as the November midterm elections approach. That number would be the lowest in the 22 years the company has asked the question, and 10 percentage points worse than the previous low point in 1992.

The mark is 14 points lower than 2010 and 19 points lower than 1994, two volatile midterm election years seen as major responses to dissatisfaction in Washington. The figure is also in line with two surveys on the same question earlier this year.

Fifty percent of voters say their particular representative deserves to win reelection. That mark, while low, is higher than in 1992, when 48 percent of voters said their representative deserved to be reelected.
