I saw Clinton and Rubio on two different episodes of a Tonight Show.
Rubio was very uncomfortable and didn't respond well to the jokes.
Clinton nearly fell over laughing when asked "do you have an e-mail addres for us to get back to you"?
If you've seen the movie "Primary Colors" about Clinton's husband's run for President, it showed Hillary as the one running the show.
If the USA wants a capable politician, Hillary will win.
I'm not saying Trump can't win, but similar candidates in the past have failed.
Understanding the system helps and Clinton really does know how it all works.
There is nobody like Obama to take the Democratic vote from her and no-one like George Bush on the Republican side.
Trump only shows up well because his Republican opponents are so poor.
