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:

Deport them !!!!!!!
And he wonders why Trump cleaned his clock??????????????
No get Muslims on the gun range they want to kill us I say target practice
no rubero it is wrong and immoral to tell a business owner how to run their business
No, it really isn’t.
KMA Rubio!
I got it ! There fukin crazy , devoid of common sense and willing to share ! Get all the Muslims out of the US ! Especially in the white house !!
Is it because Moslems never cause any trouble?
Guy needs to go back to church and learn what immoral means.
Muslims should not have guns under obamas rules. Just cause he brings them in, they are not american citizens protected under 2nd amendmant. They already know how to chop off our heads , now you want them good shots as well? This is crazy. When we go overseas we do not take our constitutional rights with us, and when they are brought here they dont acquire ours.
