Mayor Rudolph Giuliani won't cross party lines when it comes to neckwear.

Joining thousands of other New Yorkers taking advantage of post-Christmas sales, Giuliani stopped into Brooks Brothers and found the perfect tie - a dark-blue number with little white elephants."The idea is to re-establish my Republican credentials," Giuliani quipped. "I've been shopping here since I became a lawyer," Giuliani said. "It's part of the uniform."

Giuliani angered many GOP colleagues this year when he endorsed Democratic Gov. Mario Cuomo instead of the eventual winner, Republican challenger George Pataki.
