A Republican Florida state legislator expressed his doubt in the campaign of GOP presidential candidate Mitt Romney witha tweet he posted Tuesday.

State Rep. Matt Gaetz (R-Fort Walton Beach) tweeted late Tuesday afternoon that he believes President Barack Obama's decision to use Sen. John Kerry (D-Mass.) as a Romney stand-in during debate practice is a omen of where Romney's campaign is headed. Kerry lost the 2004 presidential race to George W. Bush.

Gaetz then ended the tweet with a hashtag expressing support for former Florida Gov. Jeb Bush (R) to make a presidential run in 2016.

Gaetz could not immediately be reached for comment.

This is the second tweet in recent days that Gaetz has posted expressing doubt in Romney. On Saturday, he tweeted about an email he received from the Romney campaign about a 15 percent off sale on "Romney gear." He then wrote that he believed no one was buying the "Romney gear" and ended "#sigh."

Gaetz, 30, was elected to the Florida legislature in a 2010 special election and reelected to a full term in November of that year. He serves as vice chairman of the K-20 Innovation Subcommittee and on other criminal justice, law and education related panels. Professionally, Gaetz is an attorney with a firm in Fort Walton Beach, Fla.

Gaetz is the son of state Sen. Don Gaetz (R), the president-designate of the state Senate. The older Gaetz recently made news when he put out notice that lobbyists who did not back his preferred Senate candidates would not be allowed in his office. Don Gaetz is considered to be one of the state's more conservative senators.
