The two ads from the top-tier Democratic hopeful take different tones, with one entitled “Betsy” and focusing on Republican family members in Warren's family who pledge to vote for her and another entitled “Why She Will Beat Him” which emphasizes Trump’s upper-class status growing up.

The “Betsy” clip plays audio of Warren’s brothers, niece and nephew praising the senator while clips show the Massachusetts progressive interacting with her family.

“Many of our family are Republicans, but every single one of us love Aunt Betsy and we’d do anything in the world for her,” Warren’s nephew Mark says in the ad, while sporting a Warren campaign hat.

“The whole world will be a better place with her being president, not just rich people in the world, everybody in the world,” he added at the end.

The second ad starts by contrasting Trump’s life with Warren’s, saying the president grew up in “a mansion in New York City,” receiving millions of dollars from his father, while the senator grew up in Oklahoma, and her father was a janitor.

“When someone shows you who they are, believe them,” the narrator says. “Trump’s life taught him how to get rich on the backs of others. Elizabeth Warren will be a president who works for you.”
