President Trump is in Tampa on Tuesday, and you know what that means: People are mad online.

Hundreds of the president's supporters lined up at the Florida State Fairgrounds hours before the scheduled rally, a presence that some contrasted with the crowds at 2016 Hillary Clinton campaign events.

"You didn't see lines 6+ hrs until a Hillary event like this in the dead of summer with Florida heat," @rambobiggs tweeted.

Other supporters posted pictures of their compadres holding signs such as "Impeach 'nazi' Democrats" and "Trump vs. Tramp."

For their part, Trump detractors vented their anger, deeming the event a "circus" and a "hate fest" and calling for protests.

It needs to be in FL today.

Elected officials also sparred online. Tallahassee Mayor and Democratic gubernatorial candidate Andrew Gillum renewed his call for Trump's impeachment.

Welcome back to Florida, @realDonaldTrump. My name is Andrew Gillum and I'm the only candidate for Governor who believes you deserve to be impeached. So does everyone else who RTs this. — Andrew Gillum (@AndrewGillum) July 31, 2018

Republican Congressman Matt Gaetz, R-Fort Walton Beach, one of Trump's biggest supporters in Congress, responded to Gillum by pressing him on the FBI's investigation into Tallahassee city government.

The mood online wasn't all acrimony. Attorney General Pam Bondi, an early Trump booster, tweeted her welcome to the president.

"I look forward to seeing @POTUS in our great state and welcoming him to my hometown," Bondi tweeted. "Thanks to the President's leadership, America's economy is strong and GDP growth has reached an incredible 4.1 percent."

And one Republican Party of Florida organizer tweeted out a picture of a Trump fan signing a petition in support of the president's Supreme Court nominee, Brett Kavanaugh.

Naturally, conspiracy theorists also came out of the woodwork.

A fan subreddit for the conspiracy theorist "QAnon," an anonymous purported government insider who claims to feed his followers information about the war between the "deep state" and President Trump, posted pictures of QAnon supporters at the Tampa rally.

Nonsense propagated by QAnon includes the "Pizzagate" conspiracy theory that connected Hillary Clinton to a pedophile ring and the notion that the "deep state" once tried to shoot down Air Force One with Trump aboard. The Hillsborough County GOP caused a stir earlier this month by tweeting out, then deleting a video promoting QAnon.
