A new Gallup survey finds opposition to the President of the United States, now Barack Obama, at a 16-year high.

When respondents were asked whether their vote in the upcoming midterm elections is meant to “send a message” that you support or oppose Barack Obama, 32% said their vote would signal opposition to Obama versus only 20% who said it would show support.

Gallup’s findings are similar to those under George W. Bush in 2006 when Republicans suffered losses that gave Democrats control of the House and Senate. In 2006, 18% said their vote would be a sign of support and 31% said their vote would signal opposition to Bush.

The poll also found Democratic Party enthusiasm for Obama waning. While 58% of Republicans said their vote will send a message of opposition against Obama, just 38% of Democrats said their vote signals support for the president.

Voters head to the polls in 30 days.
