As if being liked by senators and having senate endorsements is supposed to be persuasive?
Well - it depends on what the goal is. If your goal is to pass legislation, it is helpful. If your goal is to prevent being undermined and stabbed in the back for four years, it is also helpful.
If your goal is to become a tyrant or dictator, then the point is moot.
Nope, but it reflects on ability to attract followers, be likable, be able to make good deals. Otherwise nothing is accomplished. What exactly has Cruz accomplished in 3+ years you can brag about? Tried to shut down government and failed? Please list his actual accomplishments. May be I am missing something.
