Although there is much talk among political observers about the possibility of a brokered GOP convention in Tampa, Republican National Committee Communications Director Sean Spicer is not buying it. "The last time we had a brokered convention was in the 1940’s, and we’re four contests in that have awarded delegates," Mr. Spicer told me on Wednesday. "We are four weeks and four states into a process. I get that it’s the buzz, but I literally spend as much time worrying if some space alien attack happens."
