essentially a tie for santorum and romney, but romney is the real winner.
santorum only proved he could win in the state that he focused his entire campaign in.
romney proved that he could win in a state that was considered by pundits months ago to be out his reach, showing him to be more versatile. though he wouldn't have won this if it were later on,
ron paul's 3rd place isn't impressive enough to make him a frontrunner, and will only introduce him to new scrutiny.
for candidates like bachmann, perry, and gingrich, this will mean funding troubles, and eventual dropouts.
if less people drop, romney divides the "anti-romney" vote.
if more people drop, then one anti-romney candidate gets a critical mass.
ultimately, this only solidifies that romney wins.
