Ted Cruz, R-Texas, greet at a break during a Republican presidential primary debate at The University of Houston, in Houston. Cuban-Americans vote in greater percentages than any other Latinos. They have a strong presence in Washington given their overall population including three senators, two of whom were serious contenders for the presidency this year. Only one non-Cuban has been mayor of Miami since 1985. (AP Photo/David J. Phillip, File)
