This New Yorker may be your next president. Or this one. Or this one. Or even this one.

Eighty-two days after Senator Kirsten Gillibrand said during her re-election campaign that “I will serve my six-year term,” she told Stephen Colbert she was going to run for president.

Ms. Gillibrand, 52, said she was running “because as a young mom, I’m going to fight for other people’s kids as hard as I would fight for my own.”

This makes her the first New Yorker — not counting Donald Trump — to enter the race. But she may not be the last.

Michael R. Bloomberg is considering a bid. Bill de Blasio refuses to rule it out. (Governor Cuomo ruled out a run, but likes giving the impression the door is not tightly shut.)
