Iowa is viewed by many to be a must-win state for Sanders, although he enters caucus night as a slight underdog.
If the Vermont senator loses Iowa, he’s still the heavy favorite to win in New Hampshire.
However, Clinton has a huge lead among minority voters, who are expected to give her a boost once the contests turn to more diverse states like Nevada and South Carolina.
Still, Sanders signaled Monday that he could withstand a loss to Clinton in Iowa.
"We have the resources, we have the energy to continue the struggle and I think at the end of the day we're going to surprise a lot of people,” he said. “I think we're gonna win this thing."
