When you become active in the system and communicate to your representatives, and they don't vote in accordance with your values, your next responsibility is to support candidates who will. All of a sudden we were signed up until 2000." In response to the impeachment vote, MoveOn launched a "We will remember" campaign, asking its members to sign a pledge that "we will work to defeat Members of Congress who voted for impeachment or removal. To give substance to this pledge, we are also pledging, today, our maximum possible dollar contribution to opposing candidates in the year 2000." In early 1999, MoveOn continued to pursue bipartisan appeal, recruiting GOP moderate Larry Rockefeller, a New York environmental attorney and heir to the Rockefeller fortune, as the public face of a "Republican Move On" aimed at mobilizing anti-impeachment Republicans. As the 2000 elections neared, however, the organization gravitated toward the Democratic Party. 1999 also marked MoveOn's first foray into issues other than Clinton's impeachment. Following the shootings at Columbine High School near Littleton, Colorado, Blades and Boyd launched a "Gun Safety First" petition to promote the "common sense regulation of firearms," such as child safety standards for gun manufacturers and laws forcing gun-show operators to enact more-stringent background checks on buyers. In June 1999, MoveOn established its own political action committee, the MoveOn PAC, with the ability to accept contributions online via credit card. It was not the first organization to fundraise online for political candidates, but its success was unprecedented, raising $250,000 in its first five days of operation and $2 million over the course of the 2000 election to help elect four new Senators and five new House members. "That may not seem like a lot of money to most people, but it was a revolution in fundraising for campaigns from average citizens," Blades said. According to Michael Cornfield, director of the Democracy On Line Project at George Washington University, MoveOn's achievement created "a change in attitude" in the political fundraising community. "It is like a bell has gone off," he said. "The race is on. 'Let's raise money online.'" He compared MoveOn's achievement with the pioneering of direct-mail fundraising in the 1970s by conservative fundraisers such as Richard Viguerie. The most significant innovation was MoveOn's success at raising funds from small donors, with an average contribution size of $35. Prior to the Internet, small-donor fundraising was prohibitively expensive, as costs of printing and postage ate up most of the money raised.
