Chelsea Clinton and actress America Ferrera are rallying support for Hillary Clinton with a three-city campaign stop in Colorado.

When all the seats inside the University of Denver library were taken Thursday, students started plopping down on the floor to hear Hillary’s daughter and Ferrera.

Noting the young folks present, Ferrera started her speech with a scoff, adding: “And they say Hillary doesn’t inspire millennials.”

That nudge to youth voters — along with minority voters — was felt through much of Ferrera’s and Clinton’s talking points.

With millennials preferring opponent Bernie Sanders according to a USA Today/Rock the Vote poll, the campaign struggled to tamp down a potential weak spot.

One student asked Chelsea Clinton what she should tell friends who say “they don’t like your mom.”

Ferrera described Hillary as her “boo thang” and hopeful “BFF” to a crowd made up of the young, old, disabled and racially diverse.

The pair are stumping in Colorado through Sunday, stopping in Denver, Pueblo and Colorado Springs along the way. Ferrera and Clinton will meet Friday with a Latina coffee group to discuss issues important to the Latina community.

In addition to touching on abortion care, women’s rights, health care, LGBT issues, foreign policy and college debt, Clinton stressed areas where her mother and opponent Bernie Sanders differed and why she believed Hillary’s ideas were superior. Using Sanders’ free public college plan as an example, Clinton said many of his plans seemed ideal but not realistic.

“There is really a different understanding of what a president can deliver,” Clinton said. “We have to operate within political realities.”
