Amy Klobuchar, Elizabeth Warren, Pete Buttigieg and Michael Bloomberg are all studying their path forward tonight, advisers to the respective campaigns tell CNN.

Klobuchar and Warren are committed to Super Tuesday, when voters in their home states cast ballots.

But one of the biggest questions remains: What are Buttigieg and Bloomberg thinking about their next move?

All four of the candidates are scheduled to be in Selma, Alabama, for the 55th anniversary of Bloody Sunday and the annual reenactment of the bridge crossing.

Joe Biden will also be in Selma on Sunday, allowing an opportunity for conversations – or more – among all of the Democratic rivals.

The most pressing question may be for Buttigieg. He is scheduled to go to Texas, Oklahoma and California – before ending Super Tuesday in Michigan.

For now, that schedule holds. But a top Democrat close to the Buttigieg campaign acknowledged tonight that the former mayor is studying whether he has a path forward. He hasn’t reached a conclusion tonight — or if so, he hasn’t talked about it openly, even among his small circle of advisers. Buttigieg's team knows that how he leaves the race — if it comes to that — is important to his future.
