Are you not familiar with Thomas' confirmation hearing? It was brutal -- because he was black! The Democrats turned it into a "high-tech lynching".
And I can assure you, as a Texas voter, that there was absolutely no affirmative action associated with Cruz's election to the Senate. He ran as a conservative Texan. There was no pandering to the Hispanic vote; Cruz doesn't even speak Spanish well enough to pander.
Just for my clarification, When did Senator Cruz give up his Canadian citizenship, and when was the senatorial election?
