Des Moines, Iowa (CNN) - As the signs of confidence from Mitt Romney's team continued to grow, the campaign announced it would begin airing a TV advertisement in Florida.
Floridians head to the polls Jan. 31 in the fourth voting contest of the primary season. Running ads in the sprawling state is an expensive proposition for a campaign, and the announcement serves to underscore the Romney team's substantial fundraising and its general-election push.

The campaign has also sent out absentee ballots to some voters in Florida, where many votes are cast before the primary date.
The ad, "Leader," is a positive spot describing Romney as a man of "steadiness and constancy." It has previously run in Iowa and New Hampshire.
The news, released hours before Iowans cast their votes in caucuses across the state, seemed designed to emphasize Romney's painstaking campaign organization in the upcoming primary contests.
The campaign has worked to present an air of inevitability around the former Massachusetts governor, who often vows to rack up the 1,150 delegates needed to clinch the Republican nomination.
The ad also signals the Romney campaign is looking ahead to future contests, drawing a contrast to some opponents who are hoping a win in Iowa could springboard their campaigns into the top tier and spur fundraising to help continue in the primary struggle.
The effort could also help cushion Romney from a worse-than-expected finish in Iowa.
In the days before the Tuesday caucus, Romney has all but ignored his GOP opponents. Instead he has focused on broad themes of patriotism and economic turnaround, and focused his fire on President Barack Obama.
His campaign events have also changed in style, with the candidate bypassing audience questions in recent days. Instead he has rallied supporters from on stage, surrounded by his family, and separated from the audience by ropelines.
The campaign did not release information about the size of the Florida ad buy or details about where it would run.
