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:

THERE GUN RANGE IS WHERE THEY CAME FROM
It is wrong and Immoral to allow muzzies into our country! Sharia law has NO PLACE in America!!!
sorry no vote from me
No it’s not!
That’s similar to Hillary saying whatever to the audience she’s with in order to appease them… It’s wrong!
Sorry Rubio….You got your head on backwards.
It is wrong and immoral for you to be allowed to run for president of the United States…
From gun range they need to be ban from the country.
Illegal immigrants cannot own a weapon in the US, legal immigrants without a green card (or a visa) can own one if they have been issued a hunting license. Green card holders and US citizens can own one if they go through the legal channels. In this country, we allow for ALL our rights if we are legal. You cannot expect your rights and deprive someone else of theirs. That being said, I do not want to shoot at the range next to a Muslim and sadly this will hurt the ranges business, but I cannot say I agree with robbing someone of their second amendment rights if they are US citizens here legally lest they take my rights next.
You are an idiot !!
