MELVILLE, N.Y. (AP) _ New York Gov. Andrew Cuomo and Republican challenger Rob Astorino are offering sharply different visions of the state they want to lead, with one celebrating liberal policies and a rebounding economy and the other warning of a state on the brink.

This month's state party conventions mark the formal start of campaign season, and the competing narratives offered by the candidates are likely to define the race.

Endorsed by the Democrats on Wednesday, Cuomo is said to be eyeing national office. He's campaigning on his efforts to boost the economy and pass gay marriage and gun control.

Astorino, the county executive in Westchester County, says he can appeal to Republicans and Democrats alike with a campaign focusing on high taxes, government corruption and the slow economic recovery.
