I had a look at the video again. "Shock jock" Cruz's first statement wrongly gives the impression that the Senate can act unilaterally to amend the Constitution imo, Cruz said to repeal the 1st Amendment. He didn't even bother to cover his arse by using word "effectively" in conjunction with repeal 1A in first statement.
Since only the states have the constitutional authority to ratify proposed amendments to the Constitution, Cruz is politicking imo, making a lasting impression as a Paul Revere, but also knowing that people will probably not remember video by 2016.
I think you’re right. Ted Cruz is throwing bombs trying to imply that good and honorable U.S. senators have bad intentions. There’s just no place for that kind of mud slinging in politics.
