Marco Rubio continually loses his way and forgets that the main stream of American society is feeling alienated and disenfranchised. And it seems that Rubio can be bought and will change, chameleon-like, depending on who he is talking to and what he hopes to benefit from them.
Of course, the biggest mistake he made is with the Gang of Eight and the amnesty program. He made common cause with Democrats who want lots of new Latino voters who will be Democrats for life if they are given amnesty. He did this to unite with big business, which means donors, who want cheap labor. He ignored the fact that millions of illegal immigrants are flooding the country, taking jobs that Americans will do, taking lots of government services, and disrupting societies and standards. There is no attempt to assimilate, only to impose. Rubio later tried to explain after it cost him his credibility, but he was caught lying. His believability has sunk to new lows, and now he has decided to throw in with another group that is not interested in assimilating. He is simply digging a bigger and bigger hole.
Rubio against U.S. citizens again, page 2:

That’s what happens when you hang around Nikki Haley too long.
…Rubio is an idiot for NOT acknowledging the fact their ideology would/ could enable an active shooter in a gun range to go “Islamic” on the infidels at the range. Sure, they wouldn’t make it out alive, but why give them the opportunity?
Kiss my$#%&!@*Rubio!
An idiot!
FU Rubio, you big fraud!
This is debatable
If you ban a religion…than you have opened the door for all religions to be banned.
Rubio is a loser.
No its wrong that you rubio would stand up for everyone else but the American citizens.
AND WHERE WILL YOU MOUTH PIECE BE WHEN SOMEONE KILLS OTHERS AT A GUN RANGE. OH IT WILL BE WE NEED O BAN GUNS GO TO HELL RUBIO.
