Fans danced gleefully to music while guzzling beer. Smiles abounded and deafening cheers arose without warning. And, in the restroom, someone was smoking what smelled like marijuana.

Yes, it was a concert. Yes, it was a party.

But it was also a rally for Sen. Bernie Sanders, I-Vt., in the critical early voting state of Iowa, where Democrats will hold their first-in-the-nation caucuses in less than 48 hours.

The massive rally — the Sanders campaign said 3,000 people were in attendance — underscores the groundswell of support, especially from young voters, that Sanders has received during his 2020 presidential run and suggests he’s in prime position for a strong finish in Monday night’s caucuses.

Talk amongst yourselves.
