The 2016 presidential contenders are begging their Iowa supporters to get to the caucuses Monday and Donald Trump, true to form, is in-your-face about it.
"You're from Iowa," Trump told a Dubuque crowd Saturday. "Are you afraid of snow?"
A snowfall forecast to start Monday night appeared more likely to hinder the hopefuls in their rush out of Iowa than the voters who will be flocking to the caucuses in the first contest of the presidential campaign.
Still, there was every reason for candidates to be urgent about turnout in tight races on both sides.
Democrat Bernie Sanders called it a tossup with Hillary Clinton and said every caucus-goer counts.
Republican Ted Cruz directed much of his final advertising against Marco Rubio as the senators' feud grows even more bitter in the final days.
Texan Cruz, considered Trump's chief rival in Iowa, took to the airwaves to challenge the conservative credentials of Rubio, the Floridian who's running third in Iowa, according to the polls.
One ad said of Rubio: "Tax hikes. Amnesty. The Republican Obama."
"The desperation kicks in," Rubio said in response. "From my experience, when people start attacking you it's because you're doing something right."
Iowa offers only a small contingent of the delegates who will determine the nominees, but the game of expectations counts for far more than the electoral math in the state. Campaigns worked aggressively to set those expectations in their favor (meaning, lower them) for Iowa, next-up New Hampshire and beyond.
Rubio strategist Todd Harris said the Iowa goal is to end up behind the flamboyant Trump and the highly organized Cruz.
"There's no question we are feeling some wind at our back," Harris told The Associated Press. But, he added, "It's very hard to compete with the greatest show on earth and the greatest ground game in Iowa history."
In the last major preference poll before the caucuses, Trump had the support of 28 percent of likely Republican caucus-goers, with Cruz at 23 percent and Rubio at 15 percent. The Iowa Poll, published by The Des Moines Register and Bloomberg, also found Clinton with 45 percent support to Sanders' 42 percent in the Democratic race. The poll was taken Tuesday to Friday and has a margin of error of plus or minus 4 percentage points.
"I don't have to win it," Trump told CBS' "Face the Nation," before adding that he believes he has "a good chance" of victory.
He said he was confident of taking the New Hampshire primary on Feb. 9, and many others down the road. "One of the reasons that I'll win and, I think, none of the other guys will win is because I'm going to get states that they'll never get." Trump cited Pennsylvania, Ohio, Michigan, Florida, along with strong hopes for New York and Virginia.
Cruz's campaign was challenged by Iowa Secretary of State Paul Pate over a mailer sent to potential voters that seemed designed to look like an official notice warning recipients about "low expected voter turnout in your area." The mailer refers to a "voting violation" and grades the recipient's voting history and that of several neighbors, citing public records.
Pate said Cruz's campaign "misrepresents Iowa election law." There's "no such thing as an election violation related to frequency of voting," he said, and insinuating otherwise is "not in keeping in the spirit of the Iowa caucuses."
Cruz brushed off the fuss. "I will apologize to nobody for using every tool we can to encourage Iowa voters to come out and vote," he said.
