If these numbers aren't "final" they're close enough I believe. I'm going to talk Democrats first because although Clinton "won," this is an amazing performance for Sanders who no one, including yours truly, took seriously when he first announced he was running.
Hillary Clinton - 49.86% (22 delegates)
Bernie Sanders - 49.57% (21 delegates)
Martin O'Malley - 0.57% (0 delegates)
For all intents and purposes this is a dead heat tie and Martin O'Malley has announced he's done.
Now for the Republicans.
Ted Cruz - 27.65% (8 delegates)
Donald Trump - 24.31% (7 delegates)
Marco Rubio - 23.10% (7 delegates)
Ben Carson - 9.31% (3 delegates)
Rand Paul - 4.54% (1 delegates)
Jeb Bush - 2.80% (1 delegates)
Carly Fiorina - 1.86% (0 delegates)
John Kasich - 1.86% (0 delegates)
Mike Huckabee - 1.79% (0 delegates)
Chris Christie - 1.76% (0 delegates)
Rick Santorum - 0.95% (0 delegates)
Jim Gilmore - 0.01% (0 delegates)
Obviously this is a big win for Cruz but I think Rubio gains even more. The Republican Iowa Caucuses have been much further right than even the Republican Party can stomach and I'm thinking Rubio collects the support of the party stalwarts after this showing.
Mike Huckabee has announced he's done. Santorum should go with him.
