Well, there’s 5 key states if you are going to include OH.
IL, PA, OH, VA and FL.
Romney needs 3/5 to win. FL + PA + IL is probably the easiest.
If Cain locks down FL and OH, that leaves Romney with PA + IL + VA as his only out.
Cain has a solid lead in OH, has taken the lead in FL, has a slighte lead in IL and has deadlocked PA and VA.
“Cain has a solid lead in OH, has taken the lead in FL, has a slighte lead in IL and has deadlocked PA and VA.”
And keep in mind Sanatorium has something like 13% in his home state (PA). If he drops out, virtually all his voters go to Cain...
