Cruz and Rubio are ingrates. As Hispanics, they were allowed into this country so they can do landscaping and clean bathrooms, not to criticize the members of the party that gave their lives an actual purpose.
There are millions of Hispanics who are ready to pounce on the lucrative work in housekeeping, construction, and other service jobs that their betters need done, work that Americans will charge too much to do. And as a reward, govt handouts are there to supplement the meager wages that are offered.
But upstarts like Rubio & Cruz seek to upset the balance by persuading Hispanics to eschew the handouts that can be had through Democratic support, and to think of themselves as Americans, not as opportunist foreigners.
