Last night was the most exciting night in Iowa since the invention of the ethanol mandate. Ted Cruz pulled ahead in the early hours and pulled out a substantial win over Donald Trump, with Marco Rubio running a close third, only about 2,500 points behind Donald Trump. Ben Carson rounded out the top four with a decent showing (10%), and both Martin O'Malley and Mike Huckabee dropped out by night's end (both of them should probably have dropped out a month ago).
This morning, the Iowa hangover is evident. The media is gloating over Donald Trump's fallibility. Ted Cruz is probably still giving his victory speech. And the Democrats are still wondering exactly who won their caucus, as the difference between the two candidates is hovering around .2%.
So, now, what's next? Well, here are a few things you need to know about the Iowa Caucuses.
