After you have been in office two terms (Senator 12 years) you start moving away from the interests of your constituents and more to the interests of the Beltway (Establishment). The senator might not even be aware of it. In those 12 years he’s/she’s been to so many blandishments that it doesn’t take too much inner rationalization to move in that direction.
Three amnesty votes is more than enough to warrant removal from office in the primary.
South Carolina voters prove they are just like AZ voters when they return backstabbers to office repeatedly.
Keep voting for amnesty and eventually we lose our country.
