"our greatness, does not depend on Donald Trump,he is just offering fear," Obama said as he openly declares support for Hillary Clinton.

Obama named Clinton’s opponent -– calling him Donald Trump, “The Donald,” and later lumping him in with “homegrown demagogues” -- in as blunt a case against a would-be successor as a sitting president is likely to outline.

“America is already great. America is already strong. And I promise you, our strength, our greatness, does not depend on Donald Trump," Obama said. “He’s just offering slogans. And he’s offering fear.”

Outlining the future was left to Sen. Tim Kaine -– the vice-presidential nominee, nearly overshadowed in a night that would normally have belonged to him -– who broke out an impression of Trump a few times. (“Believe me!”)

Kaine went on the attack, and turned to his right and to his left in search of support.

“If any of you are looking for that party of Lincoln, we’ve got a home for you right here in the Democratic Party,” Kaine said. “We all should feel the Bern -– and we all should not want to get burned by the other guy.”

“Hillary Clinton is listo,” Kaine said, using the Spanish word for “ready.” “She’s ready to fight, she’s ready to lead, she’s ready to win.”

The man he hopes to follow in office, managed to prosecute a case against Trump while still closing with optimism.

“I know Hillary. Hillary understands. Hillary gets it,” Vice President Joe Biden said. “God willing, Hillary Clinton will write the next chapter in that journey. We are America - second to none. And we own the finish line.”
