Couched in formal language, Speaker Nancy Pelosi’s (D-CA) note to President Donald Trump suggesting he write a letter for his State of the Union speech was an explosive grenade, and likely the first sign of the fight she’ll bring to, as she calls him privately, the “whiner in chief.”

According to a Wednesday Politico report, Pelosi finally has the power and favorable polling to stand up to the President in a way that Democrats couldn’t do in the minority. She also has the requisite temperament and experience to not be intimidated. Members of her caucus describe her a “badass” and “satin and steel.”

House Majority Leader Steny Hoyer (D-MD), for one, doesn’t foresee Pelosi letting herself be pushed around by the President.

“Oh, no, no, no,” Hoyer told Politico. “She doesn’t back down to anybody.”
