Iowa Caucus Today

When The POLITICO Caucus debuted in mid-February of last year, a majority of Iowans said Wisconsin Gov. Scott Walker would win the caucuses if they were held then. Now, nearly a year later, roughly the same number — 60 percent — see Donald Trump as the winner when the votes are counted Monday night.

The 2016 Iowa caucuses have all the makings of an historic night for Democrats and Republicans, with a real possibility the current two frontrunners Hillary Clinton and Donald Trump could be beaten in what remains a very close race.
