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:

So your telling me that we had a f**e president all along and so many people knew but did nothing….Wow, so much smart people that work in the white house.
No, its not.
Do business owners not have the right to refuse business to anyone.
It’s right, and it’s smart.
Are you out of your freaking mind Marco?
Use your head dumb$#%&!@*
Ban CHRISTIANS from gun ranges!
They’re the mass shooters, war mongers and bombers!
Gaith Amri you’re an idiot plain and simple !!! We have the God given right and Constitutional right to train and protect ourselves from foreign and domestic enimies. Sorry dude but we will always be that way. The world looks at us as spoiled citizen. Hummm they don’t know us very well. We have been taught to protect ourselves from childhood. We don’t cower from danger like our current Gov wants us to. We were born American and we act like Americans no matter who doesn’t like it. We don’t sit with our known enemies. That my friend is just common sence. You open a range and let it be only Muslims allowed. Then you’ll see we American won’t much give a damn. We won’t win or complain like you people do. Sorry but what it is, is what it is. They are the enemy, it’s not their color or where they are from. So being said it’s not racism.
I agree! Every range should have several down range!
Fortunately it’s not Illegal
