Cruz sealed a victory in the Republican Iowa caucuses , winning on the strength of his relentless campaigning and support from his party 's diehard conservatives . 
If and when that happens , regardless of the political and ideological differences of their positions , they will be following in the footsteps of Ted Cruz . 
Ted Cruz has made Latino history . 
The irony of Cruz 's Latino milestone is , of course , that he does not think of himself as Latino . 
By coming in a close third , and by dint of being the last establishment friendly Republican standing , Senator Marco Rubio of Texas , has also placed himself in the position of being able to win primaries further down the line , and join Cruz as a Hispanic trailblazer . 
Unlike Cruz , Rubio does identify himself as Hispanic , and as a proud heir to the great American immigrant dream . 
Cruz , and Rubio too , have come further than any Latino politician has before them . 
Previous to Senator Cruz , the Hispanic politician who had gone the furthest in Iowa had been Bill Richardson , former Democratic Governor of New Mexico . 
The fact that Cruz , Hispanic trailblazer , is a Republican is yet another of the surprising aspects of the current electoral season .

Output: Ted Cruz
