Republican Mitt Romney is accusing President Barack Obama of engaging in "petty attacks and silly word games" just 18 days before the election.

Romney on Friday rallied a raucous crowd in Daytona Beach, Fla., saying Obama was running a small campaign.

Earlier in the day, Obama joked that a case of "Romnesia" was preventing Romney from remembering his own policy positions.

The Republican also accused Obama of having no second-term agenda. He dubbed Obama's bid, quote, "the incredible shrinking campaign."

Romney campaigned with running mate Paul Ryan. A colorful crowd of thousands greeted them - Daytona Beach is hosting its annual Biketoberfest, drawing motorcycle riders from across the country.

Romney will head to Boca Raton, Fla., on Saturday to continue preparations for Monday's debate.
