Yes, what Ted Cruz did was political terrorism. Ted Cruz held the United States hostage. His plan was to make it look like the Democrats caused the shutdown with their inability to give up on Obamacare, but in reality, the government wouldn't have shut down at all if Ted Cruz and his cohorts didn't cause it to happen.
No, not any more than any other politician. People really need to stop buying into this false "right/left" paradigm that is being pushed onto them by the media and the government. Ask yourself why people who disagree are called terrorists, racists, gun nuts, tin foil hat lunatics. Why do they want you to believe that anyone who disagrees with the agenda is dangerous and crazy? Start thinking for yourself.
