SAN DIEGO -- It is now more than just mudslinging in the race for the 50th Congressional District.

Wednesday, the Democratic Party called for an investigation into allegations of perjury and voter fraud against Republican candidate Brian Bilbray.

Democrats said the proof is in property records from three homes and Bilbray’s declaration of candidacy.

These are serious allegations against a man who has run a campaign saying San Diego is and always will be his home.

The ad states San Diego is the home where Republican congressional candidate Bilbray said he lives.

“I live in Carlsbad, taking care of my mother,” Bilbray said.

He said he has lived in the Carlsbad house since March 2005.

It is the address he used in his declaration of candidacy for the North County congressional seat.

Democrats said Bilbray does not live at that address.

“It was a convenient residence to use for this particular election since it is the 50th Congressional District," said County Democratic Party Chair Jess Durfee

In fact, there are serious questions about where Bilbray really lives.

Virginia property records show Bilbray claims a home in Alexandria, Va., as his primary residence, for tax purposes.

The same is true for a home in Imperial Beach.

Bilbray and his wife, Karen, also claim the Imperial Beach home as their primary residence.

"He's misleading us. He’s stating different things, different places, for different purposes," said Durfee.

"If these records existed since last August, and they had issues with them, then why didn't they raise them before?” asked Bilbray.

Bilbray stands by his claims of his Carlsbad residence.

Neighbors told 10News they rarely ever see Bilbray at the house, which is his mother’s home.

“He comes here occasionally to see his mother like boys will do, but he doesn't live here,” said neighbor Frank Knudsen.

“If he does live here, he must leave late at night and come back early in the morning,” said neighbor Bill Rider.

Another man, who lives right next door, said he wondered when people would catch on that Bilbray does not live here.

The Republican candidate said it’s a last-minute smear campaign.

"Frankly the attacks will continue right up until the election." Bilbray

He stands by his television ads.

There are also allegations Bilbray’s children testified they lived in Virginia for purposes of paying in-state college tuition there.

Democrats are asking the California and Virginia attorneys general to investigate.

If Bilbray lives in Virginia, he may not be eligible to run for the congressional seat here.
