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:

Thomas Laing hell yes! Let’s open that box.
Who are you wait till they come after you
No matter how much they practice they’ll still never be as good as an American gunner their best still won’t beat our worst.

Dumbass rhino
God you politicians are stupid idiots!!
I bet you don’t see any politicians on a gun range with Muslims unless they are one of the Muslims in our government!
BS
How about you go through the gun range with them! see how that turns out
Why is it everything they don’t like is immoral ?
Marco must have his head where the sun don’t shine. Surely he’s aware that Muslims want to kill Americans, and take over our country.
