While most of the prospective candidates for New York’s 2010 special Senate election are engaged in a fundraising arms war, one Democrat is urging supporters to “donate modestly.”

Scott Noren, an Ithaca, N.Y.-based oral surgeon and self-described fiscally conservative Democrat, plans to announce his Senate candidacy Tuesday at the National Press Club.

The political neophyte will have an uphill battle if he hopes to compete with the likes of fundraising powerhouse Kirsten Gillibrand, the current Democratic senator, and her other potential primary challengers, including Democratic Reps. Steve Israel, Carolyn B. Maloney and Carolyn McCarthy, while relying just on small donations.
