President Donald Trump is bleeding support among Latino voters over the same issue that drove many of them away from the Democratic Party.

The Latino polling organization Equis Research found about a third of Latinos who supported Trump last year are not committed to voting for Republican candidates in next year's midterm elections, and the survey found high grocery prices and other economic issues were driving them away, reported NPR.

"Republicans have failed to deliver on a lot of their campaign promises, particularly around lowering the cost of living," said Caitlin Jury, a research director at Equis Research. "And if they want to retain any gains they may have made among Latino voters, they need to be sure to deliver on the promises they made that maybe gave them some additional support in the last election."

Daniel Garza, who helped mobilize Latino voters behind conservative candidates as president of the Libre Initiative, said voters have soured with Trump's handling of the economy, but he believes they'll remain patient and consider GOP candidates next year.

"[Latinos] understand that there's a lag, you know, from the previous administration that continues to impact them in a way that is negative," Garza said. "And I think there is a patience with this administration for their reforms … and the changes that they put into place to take effect."

Republicans currently have narrow majorities in the House and Senate, and many of the competitive races that will decide the control of both houses of Congress are in areas with significant Latino populations.

"We have internally called Latino voters the last true swing voters," said Melissa Morales, the founder and president of the left-leaning Somos Votantes and Somos PAC. "So we do expect to see some movement one way or the other."

A large majority of Hispanic/Latino voters – 64 percent – continue to rate the U.S. economy as poor, including 32 percent who say it's very poor, while 56 percent of them feel the economy was growing worse under Trump's leadership.

"So, these are folks who were telling us they were set on voting for a Republican when we talked to them earlier this year in May," Jury said. "And now they've moved away from the Republican camp and into this neither/undecided bucket. So, [there is] movement away from Republicans, but not quite yet towards Democrats."
