Actually, we don’t really know how many Republican primary voters “buy it”. Most Republicans (and some Dems) I know agree with most of what Paul says, but they were told that he was “unelectable”. Many did not vote their conscience for this reason, or they simply did not know who he was. Of course, the same applies to varying degrees with some of the other more conservative R candidates. IOW, Republicans allowed the media to anoint one of the most liberal Republicans in the country.
I see, it is those darn ignorant voters. They just couldn’t see enlightenment.
