ALBANY, N.Y. —  In a move that could give New York's favorite daughter — Hillary Rodham Clinton — and favorite son — Rudy Giuliani — a big leg up in next year's campaign for the White House, Gov. Eliot Spitzer signed legislation Monday moving the state's presidential primary to Feb. 5.

About a dozen other states, including California and New Jersey, have already moved their primaries or caucuses to Feb. 5 or are about to do so. About a dozen more are considering such moves, setting the stage for what is quickly becoming known as "Super-Duper Tuesday" just 22 days after the leadoff Iowa caucuses.

Democrat Spitzer's move is expected to mean a big early haul of national convention delegates for Sen. Clinton and for Giuliani, the former New York City mayor. The two New Yorkers, respectively, lead national polls for the Democratic and Republican nominations.
