TOPEKA, Kan. (AP) — Democratic presidential candidate Bernie Sanders and Republican hopeful Marco Rubio are planning to come to Kansas this week ahead of the state’s presidential caucuses.

Sanders state director Shelby Iseler said Tuesday that the Vermont senator plans to have a rally Thursday evening in Lawrence at the 4H Building on the Douglas County Fairgrounds.

Some Kansas Democrats are predicting a close race in Saturday’s caucuses between Sanders and former U.S. Secretary of State Hillary Clinton.

Rubio’s campaign says he will be traveling Friday to Wichita for a rally, but the details haven’t been settled. The event would be the day before Kansas Republicans also caucus.

The Florida senator is battling businessman Donald Trump and Texas Sen. Ted Cruz for the state’s national convention delegates.
