The road to the White House begins in Iowa tonight—one of the whitest states in the country. Voters will gather at 8 p.m. Eastern time to select their picks for the Democratic and Republican nominations. Polls show tight races on both sides. Republican front-runner Donald Trump holds a small lead over Texas Senator Ted Cruz. In the Democratic race, Vermont Senator Bernie Sanders has rallied to close what was once a 40-point deficit behind Hillary Clinton. On Sunday, more than a thousand people gathered to hear Sanders’ final speech before voting begins.

Sen. Bernie Sanders: “And what this campaign is about, of course I’m here to try to win tomorrow night, try to win the Democratic nomination, try to win the general election. But more important and part of that process are millions of people coming together, black and white and Latino, gay and straight, male and female, people born in this country, people who have immigrated into this country. We will not allow Donald Trumps and the other people—we will not allow them to divide us up. We will stand together.”

The campaigns are watching an approaching winter storm that could impact voter turnout. As the first in the nation to vote on presidential hopefuls, the Iowa caucus plays an outsize role in the election cycle. Voters have been treated to months of visits from candidates and more than $150 million in political advertising. We’ll have more from Iowa after headlines.
