Andrew Rasiej, who is running for public advocate, says the incumbent, Betsy Gotbaum, is inaccessible and invisible to the public, and he has created a “videoblog” to prove it.

Yesterday morning, Mr. Rasiej sent an alert to reporters about a new Web site, http://WhereIsBetsy.com, which includes a video of Mr. Rasiej’s supporters calling Ms. Gotbaum’s office, identifying themselves as New Yorkers, and asking where they could go to see the public advocate in action. No schedule was provided.

“If I had Betsy Gotbaum’s ineffective and invisible record, I’d probably try to disappear too,” Mr. Rasiej’s spokesman, Jay Strell, said.

In a telephone conversation, Mr. Strell said Mr. Rasiej would be more active than Ms. Gotbaum: “He will be getting things done on behalf of all New Yorkers. She doesn’t have a record. She is trying to hide her public movements. If you wanted to know where your public advocate is today you wouldn’t be able to know even if you called her office.”

In response, the political consultant working on the Gotbaum re-election campaign, Hank Sheinkopf, said: “The obvious question is where’s Andrew Rasiej been? Betsy Gotbaum has been fighting for the city every day … He’s been in the nightclub business and in the Internet business and done nothing for the taxpayers of the city of New York.”

He said Ms. Gotbaum has, in fact, been busy, taking on the public school system and opposing the West Side stadium, among other projects. Mr. Sheinkopf called the new Web site “simply politics” and a “cheap shot attack.”
