LIMBAUGH: This was even done to Reagan, folks. Reagan was running for president, he and the other candidates were asked if they knew the names of various obscure heads of state -- these questions are never ever asked of Democrats, by the way. Make note of this.
The question that Trump got, Democrats will never get those questions in the normal ebb and flow of things. Hillary will never get them. Clinton will never get them, never did.
It's just they are questions that are designed to further the narrative that Republicans are just not bright, they're just not hip, they're just, and when it works on one of them, then every other Republican is going to get the same treatment.
