Prominent Hispanic conservatives say they could back Donald Trump if the presumptive GOP nominee changes his tone and walks back some of his policy positions.

Republican Latino leaders have chaffed at Trump’s call for a wall on the southern border and statements from his campaign launch about rapists and criminals coming across the border from Mexico.

The tone and policy positions have contributed to Trump’s unpopularity with Hispanics. Trump trailed Clinton by 39 points among Hispanic voters in a Fox News Latino poll released on Friday.

But prominent voices in the conservative Hispanic world say they’re ready to move toward Trump if he can move toward them.
