A series of political dominoes could fall in the coming weeks if Attorney General Letitia James launches a campaign for New York state governor. One of those likely dominoes to fall - a bid for attorney general by law professor Zephyr Teachout. 

Teachout confirmed on Saturday, first to the Times Union and later on Twitter, that she will run for the attorney general post if James is seeking higher office in 2022. 

Teachout has previously run for governor in a 2014 primary against then-incumbent Andrew Cuomo. In 2016, she ran unsuccessfully for a Hudson Valley House seat against Republican John Faso. And in 2018, she was in the crowded field for attorney general after the office was vacated by Eric Schneiderman, who resigned amid allegations of sexual abuse. 

It's likely an attorney general primary would once again be a hotly contested race on the Democratic side given the prominence and power of the office.
