After months of campaigning, the nation's first caucuses are here, and the result is far from decided. Polls out of Iowa have shown shifting front-runners, and four of the candidates have been tied up in Washington for Trump's impeachment trial. Here's where they stand.
Bennet
The senator from Colorado plans to spend Iowa caucus night in New Hampshire, where he said he's going "all in." That state's primary is Feb. 11.
Biden
The former vice president has consistently been at or near the top of polls in Iowa, but his name is also wrapped up in the impeachment trial.
Bloomberg
The former New York mayor entered the race late, and he's skipping the Iowa caucuses and New Hampshire primary to focus on later-voting states.
Buttigieg
