It's likely been a long time since Jon Bon Jovi played a venue as small as the State Theater in St. Petersburg -- much less as the opening act to the headliner.

"The future Vice President of the United States, Tim Kaine," Bon Jovi said.

Understanding his audience, Kaine kept his message short but focused on the importance of voters in Florida.

"If you put your votes behind Hillary Clinton, it is done. She will be President," Kaine said.

Kaine finished the four song set by Bon Jovi, joining the band on his harmonica.

Campaign concerts are part of the strategic sprint across key battleground states in the short time before the election. Donald Trump wasn't impressed by the concerts and their crowds.

"We don't need Jay-Z to fill up arenas. We do it the old fashioned way. We do it the old fashioned way because you love what we're saying and you want to make America great again," Trump said.

Trump will be back in the Bay Area Monday morning, stopping at the Sarasota Fairgrounds for a rally at 11 a.m.

Jimmy Buffett will be in St. Petersburg Monday evening to perform a concert in support of Hillary Clinton and other Democrats, at Albert Whitted Park at 5:30 P.M.
