The former Florida governor’s trip has been framed as a Trump contrast tour, designed to highlight the sharp differences between his plan and the current Republican front-runner’s. Bush previewed the message last week…

Bush is the “only candidate in the presidential field who has put forward a serious, conservative, comprehensive set of solutions to fix our broken immigration system,” the campaign said in its guidance to reporters on Monday’s trip. “His plan stands in stark contrast to the $500 billion+ plan offered by Donald Trump,” it said.

Bush’s visit to McAllen had been scheduled for weeks, to attend a fundraiser. The public events were added after the fundraiser was scheduled. Aides had suggested privately for weeks that Bush wouldn’t be making a border visit, because he’s made such trips before.
