Republican House candidate George Demos is reporting $1 million in cash on hand from a personal loan, according to his Federal Elections Commission filing.

The filing, made public today, comes after Demos indicated he would seek the GOP nomination in the first congressional district in Suffolk County, which is currently held by Democratic Rep. Tim Bishop.

His spokesman, Rob Cole, had previously indicated that Demos was prepared to make a significant investment in the race.

Demos first ran in 2010, but lost a contentious Republican primary that included Randy Altschuler and Christoper Cox, the son of Republican Chairman Ed Cox.

Demos, a former SEC prosecutor, was close to seeking the seat in 2012, but dropped out in May of that year to get married.

Demos will likely have his work cut out for him in the coming months, with Republicans — on a background source basis for now — knocking his candidacy.

Nationally, Republicans believe Bishop is vulnerable considering an ethics invesgitation into his office securing a fireworks permit for a constituent who donated to the lawmaker’s re-election campaign.

Bishop has denied wrongdoing and donated the contribution to charity.
