CLERMONT, Fla. -

A Lake County couple is fighting back after vandals defaced an Obama 2012 campaign sign in their front yard.

Vandals spray-painted "Nobama" over the Costigans' sign outside their house on Nellie Oaks Bend in Clermont.

"I felt like someone was trying to intimidate me to keep me from expressing my opinion and my point of view," said Eileen Costigan. "Obviously the person who did this was too cowardly to come up to me and talk to my face."

Costigan said she's keeping the sign posted, but she added her own sign, which is a message to the vandals.

The sign reads, "To the person who defaced our yard sign: This is the USA. US soldiers are sacrificing our lives to protect our democracy. If you would like to live in a country where there's only one political party and only one point of view is allowed, then move there." It's signed "Charlie and Eileen Costigan."

"I hope that, that person, and maybe some other people who might be feeling the same way might see it and it may spark them to think a little differently," Costigan said.

The Lake County Democratic office told Local 6 there have been reports of other Obama signs in the area being defaced.

The Rasmussen Reports daily Presidential Tracking Poll for Friday shows President Obama attracting support from 49% of voters nationwide, while Mitt Romney earns the vote from 47%.  Romney will be in Central Florida on Saturday for an event.
