American voters are angry with both the White House and Republican lawmakers for their bungled handling of the growing crisis on the border between the U.S. and Mexico, according to a new Washington Post-ABC News poll.

The survey, which was conducted from July 9-13 and has a margin of error of plus or minus 3.5 percentage points, found that 58 percent of survey respondents disapprove of President Obama's handling of the sudden surge of unaccompanied minors who have flooded the border.

And of the self-identified Latino adults surveyed in the report, 54 percent say they are definitely unhappy with the White House's handling of the situation.

Republican lawmakers score even worse than the president, with roughly 66 percent of survey respondents saying they are dissatisfied with the GOP's attempt to sort out the crisis. Unsurprisingly, nearly half of the self-identified Republican adults surveyed in the poll say they're unhappy with how their party leaders are dealing with the issue.

The survey's release coincides with with House Speaker John Boehner, R-Ohio, saying Tuesday that he hopes to unveil a new immigration bill sometime by the end of this week.

"I expect that by the end of this week, we'll have some answers," he said.

But as even as the GOP struggles with its own poor grades from its mishandling of the border crisis, Obama's low marks are especially painful considering that he won nearly 71 percent of the Latino vote after campaigning endlessly on the issue.

A separate Wall Street Journal/NBC News survey conducted earlier this year found that the president's approval rating among Latinos has fallen to 44 percent, down from its previous 67 percent in January 2013.

However, if it's any consolation for the president, roughly 53 percent of the 1,016 U.S. adults surveyed in the Washington Post-ABC News poll approve of the president's request for $3.7 billion in funding to address the burgeoning crisis involving unaccompanied minors on the border. Only 43 percent of respondents oppose the proposal.

Republican lawmakers have of course objected to the president's multibillion-dollar proposal, saying that the money would just be wasted if it isn't used to stem the flow of illegal immigrants crossing the border.

White House Press secretary Josh Earnest defended the administration's plan Monday, saying the proposal “is something that Republicans themselves have advocated for, pressing this administration to mobilize resources to meet this urgent humanitarian need and enforce the law. That's exactly what we're seeking to do, and that's exactly what these additional resources would allows us to do more effectively.”

Of the self-identified Latino voters surveyed in the report, 54 percent support the president's pricey plan, while 43 percent oppose it.

Meanwhile, as Democratic and Republican lawmakers battle over the best approach to dealing with the border crisis, President Obama and his staff are preparing for a 15-day vacation at Martha's Vineyard.
