The Democrats are looking BAD (poll wise) even along the Texas-Mexican border.
Cuellar’s numbers are down, and like some other have mentioned, the Texans with Mexican heritage are NOT happy with all these even MORE third-worlders, and crime riddled thug cultures from Central America!
Cuellar is simply playing to his constituents, but like all good politicians (especially Democrats), as soon as he is re-elected and back in the safe confines of D.C., he will sing whatever song The Won wants him to sing!
