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:

Why
Not when we are at war with them, and we are. Yes, there are Muslims who are on our side who want to use gun ranges. But in times of war, you can’t take the chance. We’ve had U.S. Muslim soldiers already go postal and shoot their fellow soldiers up. Just can’t take the risk.
BS
Yeah, Lit’l Marco, let’s train Muslins to fight against us!
No they are practicing so they can kill us. They should not even own guns in this country. They are not citizens in this country.
Its wrong and Illegal to allow Muslims into the country.
Wrong
Bad statement Rubia.
You be smoking the wrong stuff Traitor.Muslims need to be deported back to their gritty cities. Though it ruins the elites plan to steal all the oil.
Rubio you’re a good guy.
But you need to grow some balls!!!
Protect this country from ones who are trying to destroy it.
Go after Obama!!!
