He shares a few positions with Republicans, but seems to have more differences than common ground.
I would be very happy to see Republicans in Texas kick him off of their ticket, but it's really up to Republican voters there to decide if they want him to represent them.
Every two years, a small group of GOP lackeys put up someone against him in the primary and claim that "this is the year we're going to primary out Paul". Their guy always gets raped in the primary. It's as consistent as the tides. Y'all are stuck with Paul.
