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:

Don’t vote Rubio.
Is it also wrong to ban you from being the president? Go hang out with Romney,the loser ,you’re going to have sooo much in common.
Just pandering for the Muslim vote.
His liberal slip is showing again. Lefty!
I wish this punk would go away. He’s such an idiot and so immature. It’s not only muslims he wants more of. Soon we will have all of Cuba here and 99% of Mexico.
Are you serious?
Never had one for a target but lf they are a terrorist why not.
BUT THIS IS RIGHT AND MORAL…. YOUR KIND OF IDIOTIC LOGIC IS WHY I’M LEAVING THE “PARTY’
VOTE TRUMP!!!!!!!
Ban muslims from America
We should use you for a target
