Chances are that person wasn’t a Republican or a conservative at all. Liberals love to do that, pretend that they are conservative and then try to wheedle you on one of their pet issues.
I would say I am 99.999999 percent certain that the caller was not a Republican or conservative. They always give themselves away as soon as they the little three letter word “but” after they claim to be a Republican or a a conservative. They need to try a lot harder to convince me.
