Scott’s political committee, Let’s Get to Work, is releasing an ad that will begin airing Monday, which uses past statements from Florida Democrats slamming Crist, the Tampa Bay Times reported.
The spot quotes five Democrats, including Alex Sink, who lost the 2010 governor’s race to Scott, Rep. Kendrick Meek (Fla.) and former Vice President Al Gore.
"He can't be trusted,” Meek is quoted as saying in the ad.
"He failed to layout a business plan to get Florida out of its worst recession,” Sink said.
"It's a little unusual to have someone flip-flop and… then flop-flip,” Gore said.
Crist’s announcement he will challenge Scott has been widely expected, and early polling has shown him leading in a matchup against the Florida governor, whose approval rating has dropped.
