Ted Cruz has a message for Republican delegates: I can win over Donald Trump’s supporters even if I don’t win over Trump himself.

“If it ends up, as I think probably will happen, at a contested convention that we earn a majority, it’s going to be critically important then to keep the Donald Trump supporters energized and engaged,” the Texas senator told Mark Halperin and John Heilemann in an interview for Bloomberg Television’s With All Due Respect.

Cruz posited that one of the reasons he’s “the last man standing” against the front-runner is that he’s “the only candidate who’s competed effectively” for the blue-collar workers who form the heart of Trump’s base.

“The issues that energize and excite the Trump voters—illegal immigration, securing the border, keeping this country safe and bringing jobs back to America—bringing them back from China, back from Mexico—those issues are right at the heart of our campaign,” he said. “So I believe if I earn a majority of the delegates in Cleveland, that we are going to be able to continue to energize and unite those Trump supporters and get them to come out and vote in November.”
