Rubio Says Des Moines Register Endorsement Doesn't Make Him Establishment Pick

Rubio "has the potential to chart a new direction" for Republicans, paper says.

Rubio "has the potential to chart a new direction" for Republicans, the paper's editorial board concluded in its endorsement, and "represents his party's best hope" to retake the White House in November.

Asked if Trump's standing hurts his chances, Rubio, who has received endorsements from more than a dozen members of Congress, said voters should resist supporting the "next person in line or who the people in Washington tell us we're supposed to be voting for."

Rubio, who will appear Monday with Sen. Joni Ernst, R-Iowa, said Ernst hasn't taught him how to "make 'em squeal" in Washington -- a campaign pledge from the freshman senator who grew up on a hog farm.

"You're not going to see ads like that from me," he laughed. "I didn't grow up around hogs."
