The so called Hispanic vote is not and never will be a solid voting block.
S. Americans are not Mexicans, have very little in common with them. If I had to guess Id say that is true, Rubio and Bush would pull Hispanic votes but never the Ca. Hispanics or IL or other Mexican loaded states. Texas is Tex Mex and never confuse them with others LOL.
It seems the Hispanic vote will be split, as always, with the Mexican vote going RAT and by a large majority the others going R. Thats my guess at this time.
RAT in disguise Cornyn got 48% of the Hispanic vote in his last election.
