ALBANY – Nineteen months after ending his disastrous run for the presidency, Rudolph W. Giuliani is clearing a path for a possible race for governor in 2010, believing public anger at an ineffectual Albany and unease over the economy could create ideal conditions for a Republican to reclaim the governor’s mansion.
Mr. Giuliani has told associates that he will decide on a candidacy within 30 to 60 days, as he weighs whether he can be elected statewide and what impact another campaign would have on his business interests.
