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:

hell not it isn’t it is just common sense. why put a gun in their hands?????
this is why he will never get elected
HELL NO IT IS NOT WRONG. BUT YOU ARE Marco Rubio.
Muslims should not be allowed on American soil.
Oh and by the way if you become President you can build your own range beside the White House! That way you can invite the Muslims for lunch and shooting sports !
Oh shut up rubio!
He is insane
F**k you,
No it is Justified, as Muslims are REFUSING TO STOP OTHER MUSLIMS on acts of Terror therefore ALL MUSLIMS ARE TERRORIST…just NOT all act as such. Rubio is NO BETTER THAN OBAMA, Thankfully he will NOT BE Elected as President!
This son of a$#%&!@*really needs help , Obama brings them in and he will train and arm them .
