I've caught third-party fever. It's quite contagious, apparently. First, Mike Bloomberg, a Republican candidate for mayor, created a new political party -- devoted to education -- and anointed himself as its candidate. Not to be outdone, Democratic candidate Alan Hevesi developed a bad case of the fever and also formed an education party. The party then promptly selected a guy named Alan Hevesi as its candidate. Not to be outdone, I have decided to form my own party and run as its candidate in November. But before delving into this weighty process, I called the Board of Elections, whose spokeswoman immediately threw several wrenches into my plan for five-borough domination. "You have to collect 7,500 signatures by Aug. 21 and those signatures have to be CLEAN," Naomi Bernstein said, explaining that a "clean" signer is someone who has not signed any other candidate's petition already. "It's not nearly as easy as it sounds," Bernstein said. That's why armies of "volunteers" from Hevesi's "Education Party" and Bloomberg's "Education First" party are fanning across the city hounding you for signatures. Next, you have to come up with an issue. Hevesi and Bloomberg paid a lot on polls that show that education is a top priority, and when you've spent so much money on a poll, you obviously want to implement its findings. Lacking money for a sophisticated poll, I flipped through dozens of past MetroGnome columns and found that I have plenty of "issues" that are important to me: those thin ad trucks that drive Midtown all day, people who litter, drivers who honk their horn THE VERY SECOND the light turns green, blocking the Second Avenue Subway in favor of expanding the Second Avenue Deli, and the shocking inability of American eaters to beat the Japanese in hot-dog competitions. These are important issues, but they are hardly the bedrock principles on which political movements are built. So I placed another call to Bernstein, who suggested a compelling party theme. "You should call it the `I Love Gersh' party," she said, implying strongly that she, in fact, did. There is, of course, precedence for newspapermen running for the city's highest office. In 1969, Norman Mailer and Jimmy Breslin ran for Mayor and City Council president -- but they foolishly ran in a crowded Democratic primary rather than forming their own party (although they did steal several of my issues, such as making New York City the 51st state and promising "No More Bulls--t!"). I called both Mailer and Breslin for advice, but neither called me back. Obviously, losing to Mario Procaccino is still an open wound. Lastly, Bernstein told me that in addition to the name of my party, my petitions must bear the logo of my party. Just as the Democrats have their donkey, the Republicans have their elephant and the Marijuana Reformists have their six-pointed leaf, I would need a design that would tell voters, in one glance, why they should love Gersh, too. I called a graphic artist and ordered a logo that would capture the hopes, dreams and runaway egotism of a fledgling political movement devoted solely to me. Artist Kenny Dinkin understood the job implicitly: "I chose the bagel because you have always fought against declining bagel quality in New York," Dinkin said. "It's signifies your integrity, genuine humanity and complex neuroses." So now that we have a name and a logo, all I need is the single issue that is going to get me to Gracie Mansion. So I need your help. See that email address below? Use it. Hold up your end by telling me what single issue I should address, and I'll hold up mine by collecting signatures to get on the ballot in November. Even Bernstein thought it was a good idea. "At the very least," she said, "you'll get material for a few good columns." "Good" columns? Man, that woman flatters me. --30-- email: gershny@yahoo.com
