Why should we take advice from a writer we never heard of before?
Maybe because the message is more important than the messenger? Or has modern culture simply destroyed that old-fashioned notion? Personally, I believe that good information and ideas could come from anyone at any time. Better to focus more on the actual idea than the source.
Limiting the number of candidates might be wise, but impractical in reality, IMHO. The thing we need to VERY diligently keep in mind is avoiding the MSM choosing our candidate. They want a weak centrist (like Jeb, Christie, or Mitt) to lose in spectacular fashion to their minority-hero of the moment (Hillary). Let's not let that happen this time around, shall we?
