Seventy-two percent of voters who disapprove of the job Obama, congressional Democrats and congressional Republicans are doing say they’d vote for the GOP candidate for U.S. House in their district if the election were held today, according to a new Washington Post-ABC News poll released Tuesday. Just 14 percent say they’d vote for the Democrat…

They lean heavily Republican. Thirty-four percent identify as Republicans and another 38 percent are independents who lean Republican. Just 13 percent are independents with no lean and just 10 percent are Democrats. Seventy-one percent oppose the federal health-care law.

The haters matter because they constitute a significant and growing share of the electorate, due to sunken approval ratings for both Obama and congressional Republicans. Together they make up about a third (34 percent) of all voters. A month before the 2010 GOP wave election that swept House Democrats from power, the haters constituted only 28 percent of the electorate.

The haters’ clear support for Republican candidates means GOP voters’ grumbling about its party’s maneuverings in Congress – past polling shows the dissatisfaction is wide-ranging, from seeing the party as too liberal or too conservative — does not mean they are ready to abandon the party’s candidates at the ballot box. Quite the opposite, in fact. These voters will come home in the end, the data suggest.
