But will it be Hillary or Bernie?

CNN reported Wednesday morning that Clinton's campaign expects to lose in Nebraska, as well as in Kansas and Maine, which also hold Democratic caucuses this weekend.

Clinton's Nebraska staff has since questioned that report, and CNN changed it later Wednesday, quoting spokesman Brian Fallon who said Sanders is "going to have some victories in the week ahead."

Both candidates could see boosts from major rallies scheduled for this week.

Sanders is scheduled to appear at the Lied Center at 1 p.m. Thursday, and former President Bill Clinton will campaign for his wife in Lincoln and Omaha on Friday.

Former first daughter Chelsea Clinton also appeared in the two cities earlier this week, and Hillary Clinton spoke to about 800 people in Omaha in December.

Can't make the caucus?

Tuesday was the last day for people who can't participate in the caucus to submit absentee preference cards, but voters can still weigh in ceremonially during the May 10 primary election.

And, of course, you can vote for president in the general election Nov. 8.
