A big coup for Rudy Giuliani: He's just signed up D.C. lobbyist Dirk Van Dongen as his D.C. finance chair, Roll Call reports. The move is significant because the acquisition of Van Dongen, one of President Bush's top fundraisers, shows that Giuliani is beginning to have some success winning over Bush money people, who are being fiercely fought over by the GOP campaigns. Giuliani has obvious ties to man big Wall Street GOP donors from his two terms as mayor of New York City, but success in winning over members of the national GOP fundraising network -- not to say members of the inside-the-beltway GOP fundraising establishment -- has been far less assured. Meanwhile, an adviser to Giuliani also tells Roll Call that many more acquisitions will be announced in coming weeks.
