Democratic Presidential Candidate Hillary Clinton will hold what her campaign calls a "grassroots" organizational meeting at Broward College today in South Florida.

It's a chance for Clinton to make her pitch to Democrats and, specifically, Hispanics.

Clinton's pitch, called Latinos for Hillary, will also extend to Hispanic lawmakers and elected officials, and will include an address next week to the Congressional Hispanic Caucus Institute's annual meeting in Washington.

Meanwhile in Miami, the enthusiasm is already there.

"We're really excited about Hillary," said volunteer Verna Johnson.

Others are still weighing their options.

"I'm trying to see which candidate I'm going to vote for," said Brian Kaam, a freshman at Florida Atlantic University.

Kaam drove for an hour to be first in line to see Hillary Clinton, but he admits he's considering a choice that's not even in the race.

"If Joe Biden steps in, I'll probably vote for Joe Biden," Kaam said.

Statements like that could be bad news for Clinton.

"Think of Joe Biden," said Broward College Political Science Professor Kevin Walsh. "He's Vice President of the United States. He's got a very good relationship with President Obama and President Obama supporters are very likely to listen to him, the President, if he were to kind of lean in the direction of Joe Biden. I think it'd be a big help to Biden and I think Hillary sees that as a real threat, a legitimate threat."

Experts said what Clinton says at her rally could be critical. They said it's important for her to boost enthusiasm now, especially when her poll numbers are slipping.
