In this Sept. 4, 2012, photo, San Antonio Mayor Julian Castro addresses the Democratic National Convention in Charlotte, N.C. The Hispanics with the highest profiles in this year’s political conventions stand as opposites in a cultural and political split that has divided millions of U.S. Latinos for decades. Cuban American Sen. Marco Rubio of Florida introduced Mitt Romney at the GOP’s convention last week in Tampa, Fla. Castro, a Mexican-American, delivered the Democrats’ keynote speech in Charlotte on Tuesday. They are often lumped together as Hispanics. But Rubio and Castro are emblematic of acute political distinctions between Cuban-Americans and Mexican-Americans. (AP Photo/J. Scott Applewhite)
