The two draw from similar segments of the Republican primary electorate—sometimes, almost too similar. In the video launching his presidential bid, Cruz made a passing reference to “make America great again,” which has since become the Trump campaign’s slogan. Trump applied for a trademark on the phrase shortly after the 2012 election. The Texas senator’s use of the phrase, even in passing, prompted the Trump Organization to reach out and warn the Cruz camp in a friendly manner not to use it again, according to a Trump campaign insider.
