Tea Party favorite and newly-elected Sen. Ted Cruz (R-TX) took his oath of office today – and immediately moved to take on President Obama’s chief legislative accomplishment, Obamacare. Cruz is the first Hispanic to serve as a Texas Senator.

His first bill, Cruz said, would move to strike “every syllable of every word” of Obamacare. With the retirement of Sen. Jim DeMint (R-SC) and the increasing battle between Tea Party conservatives and Republican Party establishment types, Cruz is set to become a leader early in his tenure – and grassroots conservatives are already rallying to his cause.

Cruz, 42, is slated to appear on Fox News Sunday. He is a Harvard Law graduate, the first Hispanic to clerk for a Chief Justice of the Supreme Court (William Rehnquist), and a former Department of Justice lawyer. His rise has been so swift that he is already vice-chairman of the National Republican Senatorial Committee.
