Jonathan Karl explains why: “Gingrich firmly believes that staying in the race is the best way to prevent Mitt Romney from clinching the nomination before the convention in August. And he actually may have a point.”
Said Gingrich: “We’re actually helping because between us — Santorum and I — are stopping Romney.”
“Gingrich knows that it is virtually impossible for him, or Santorum for that matter, to beat Romney on delegates, but he makes the case — and it is not far-fetched — that unless Romney starts winning delegates at a faster pace he won’t clinch nomination by end the end of the primaries.”
In fact, ABC News notes Santorum’s best chance may be Gingrich’s remaining in the race.
