The second biggest item on the ballot this year is the vote on medical marijuana.

Proponents and opponents are pouring millions of dollars into the fight and making a last-minute pitch on the night before Election Day.

The "Yes on 2" campaign hasn't held any election events or rallies the last few days. Instead, representatives have spent the time making calls and making a social media push on Facebook and Twitter.

The main man behind Amendment 2, John Morgan, has not done any public speaking events over the last few days.

Morgan has been debating and campaigning across the state in recent months. He said it's a personal fight for his brother, Tim, who was paralyzed and needs medical marijuana to help with the pain.

"I see this as my mission," Morgan said. "I see this as philanthropy."

The opposition has been almost as vocal and has raised almost as much money as proponents of Amendment 2.

"Vote No on 2" is using local law enforcement, doctors and others to warn people of consequences Amendment 2 could have on the state.

Seminole County Sheriff Don Eslinger doesn’t think medical marijuana should be in Florida's constitution.

"There's no age requirement on a qualifying patient," Eslinger said. "There's no state relationship or certification for a personal caregiver. There's no residency requirement. It's not just for Florida residents; it's for whoever."

Funding for support and opposition of Amendment 2 has come from two main parties.

Morgan has spent about $5 million of his money. In total, People United for Medical Marijuana has raised about $8 million.

Sheldon Adelson, a billionaire from Las Vegas, has almost solely funded the efforts to prevent the amendment from passing, donating about $5.5 million.

The anti-medical marijuana groups have raised about $6.3 million.

The family that owns Publix has donated $640,000 through the Carol Jenkins Barnett Family Trust, and Mel Sembler has donated $100,000.

The latest News 13 Florida Decides Poll shows support is slipping for medical marijuana, with 46 percent of likely voters in favor and 43 percent of voters against. Seven percent of likely voters remained undecided.

News 13 Republican political analyst Michelle Ertel, who is against medical marijuana, said that in order to for the bill to pass, it will need support from the young and the old. The elderly vote makes up about 33 percent of Florida's electorate.

"I think there are plenty of elderly people who are buying the hype that this is going to take care of their issues," Ertel said. "And, of course, the younger people are hoping this leads to full on legalization."

The "Yes on 2" campaign will hold its Election Day party in St. Petersburg, just blocks away from where Democratic gubernatorial candidate Charlie Crist will hold his watch party.

Crist is a former employee of Morgan and Morgan.

The "Vote No on 2" campaign said it will not hold an event on Election Day.
