And back here at home tonight, and to an abc news investigation, and it involves your money. Hundreds of thousands of americans were revved up after the democratic and republican conventions, ready to donate to their favorite candidate. And to their party. But some of their dollars went not to the candidates, but to a different kind of white house. Watch what happens as abc's chief investigative correspondent brian ross goes in search of your money. Reporter: In the wake of the balloons and the confetti, hundreds of thousands of americans, mostly small donors, went online to send in campaign contributions. But for anyone who sent money to the democratic national committee.Org, that money did not go to the democrats. Nor did money sent to the republican national committee.Org go to the republicans. The sites seem like the real thing but they are not. Despite the official looking graphics and pictures and requests for contributions. Republicans and democrats were not aware of the copy cat sites until we showed them. Is this the republican national committee's website? It is not. Reporter: An abc news investigation found that both suspect sites are run out of this single family house in massachusetts by this man, donald peltier. A fuel truck delivery man by day and an internet slight of hand artist by night, who acknowledged he keeps the money sent in. Peltier own what are called the domain names, only in the small print would donors be able to see the words "not connected with any federal elections." They're being scammed, duped, ripped off. Reporter: And dozens of other look alike sites have already popped up, as reported by politico and the national can journal. These sites have refunded dozens of donations after taking in some $570,000, none of which went to the candidate. Reti retiree jim sent $250 to the site he thought was mitt romney's. I'm stunned that the contribution that I made didn't go where I wanted it to go. Reporter: In the case of the massachusetts man, with the political party sites, donald peltier, he did not want to talk with me. Drove away into his backyard and then called 911 to complain. I don't want to talk to him. I don't want anything to do with him. I want him off my property. Reporter: The police came, but found no problem with the presence of abc news. They're on the sidewalk, on public land. Reporter: Both the republicans and the democrats tell us they're going to court to shut down the lookalike websites, david. Never good when they don't want to talk to you. How do people at home protect themselves if they want to donate? Reporter: Look on the websites for a phone number and address and it won't be a small town in massachusetts. Should be something in washington, d.C. Good tips.
