Michele Bachmann is on the air in Iowa today for the first time in months with an ad comparing the Minnesota lawmaker to former British Prime Minister Margaret Thatcher.

“America’s Iron Lady” is a positive ad that calls Bachmann “the only consistent conservative fighter” in the race and emphasizes her Iowa roots.

The narrator never mentions Thatcher, but at one point a picture of the iconic British leader (currently being portrayed in theaters by Meryl Streep) appears alongside Bachmann.

In the past few days Bachmann has repeatedly compared herself to the original “Iron Lady.” While Bachmann largely avoided discussions of gender earlier in the race, she is now hammering on the theme, stressing the appeal of a “strong woman in the White House.”

But this new tack and the ad that goes with it — which imparts no new information about Bachmann and does not attack any other candidate — is likely too little, too late. The woman who won the Ames Straw Poll in August is now polling at 7 percent, sixth place.
