there is no Reagan in this election, and there is no one close to Reagan in this election, so conservatives will have to look for the likes of Brownback and Newt, who don't have a chance of winning a general election.
We will probably never see the likes of another Reagan, but there are candidates who are very close to him on the issues. Why write them off at this premature stage, and stampede to a candidate who is basically a Democrat of circa 1975 or '80 vintage? Rudy would be to the left of any Republican Presidential candidate in history!
