In unreleased Iowa poll, Sanders finishes 1st, Biden 4th

Remember that final poll of Iowa Democrats from CNN and the Des Moines Register that wasn't released because of an interviewing error? Well, FiveThirtyEight reportedly confirmed the final results.

It would've been good news for Sens. Bernie Sanders and Elizabeth Warren, who led the pack with 22 percent and 18 percent, respectively. That falls in line with an earlier report that media outlets increased their coverage of Warren after glimpsing the numbers.
