Short on cash and out of states where he can make a stand in primary contests, Newt Gingrich is steering his long-shot White House bid right into the weeds, until he can potentially crash Mitt Romney’s parade.

The former House speaker has adopted a new convention-or-bust strategy that puts him on a course to play party spoiler at the Republican National Convention in Tampa in August. It is a plan that rests on the slim hope that he could curry favor with a GOP establishment that is yearning for the race to be over.

But Gingrich, who must contend with the sometimes complicated Republican National Committee rules as he seeks to amass delegates, still sees a hitch that could catapult him to the top spot.
