Other than a brokered convention, this is a delegate race, and every single one matters. Why no one else is pursuing these small ones is beyond me. There’s about 80 delegates total here in these island caucuses in the next couple of weeks. That adds up!

Probably because none of the three “non-Romneys” got into the race with a realistic thought of actually winning the nod:
(a) The Newtster got in so as to increase his books sales and speaking fees.
(b) Santo got in so as to raise his name recongition as a DC lobbyist and possible 2016 candidate.
(c) Ronny the P got in so as to bolster the Libertarian movement.
In other words, none of the three ever expected to be where he is today. Therefore, none of them bothered to solicit support in all “57 states” of the Union.
