These are three things I think have, as Lew Archer would say, a bifurcating root.
Several times in talking about running as an underdog speaking out on bedrock conservative issues, Rick Santorum drew analogies with Ronald Reagan in 1976. Pundits would of course note that there was a flaw in this, that Reagan didn't win his honmination in 1976.
For a couple of days, Joe S last week talked about hwo Santorum needed to quit and save himself to run another day, that he is joung enough to run in 2016 or 2020 unless he damages his own brand or allows Romney to destroy his brand with "carpet bomb" negative ads.
Bella Santorum was hospitalized wih a case of pnuemonia and Santorum fir interupted and then suspended his campaign.
