Rubio is not now and never will be a “conservative traitor.”
He would have to have been a conservative in the first place for that.
He was open about his open borders agenda in speeches he made to Spanish language audiences from the beginning. Links to many of those speeches on YouTube were posted here during his campaign.
There were and are a lot of people who were too credulous during his campaign. We showed them exactly what he was really about in his own words and then they were shocked when it turned out to be true. Kind of like the shock a lot of people who thought Obamacare was going to give them Bethesda care for almost free are now recieving.
