DES MOINES, Iowa (AP) — Florida Sen. Marco Rubio is upbeat entering the final stretch of his Iowa campaign, while trying to stay realistic about the outcome of Monday's contest.
During an interview on CBS's "Face the Nation," Rubio built expectations for rival Sen. Ted Cruz as "clearly the front-runner," while trying to trim his own prospects the day before the caucuses.
A Des Moines Register/Bloomberg Politics poll of likely Republican caucus goers published Saturday showed Cruz trailing billionaire Donald Trump and Rubio in solid third.
Rubio is wrapping up a nine-day blitz of Iowa on Sunday with events in Cedar Falls, Cedar Rapids and Davenport.
Rubio tells CBS: "The crowds are growing. The people signing up are growing. Our campaign structure feels good about it...We'll have a strong showing on Monday night."
