“Mama Grizzlies” is a metaphor used by 2008 Republican vice presidential nominee Sarah Palin for conservative women.
In speeches during the 2010 midterm election campaign, Palin challenged these “mama grizzlies” to rise up and “take this country back” and invoked her 2008 acceptance speech where she compared herself to a pit bull.
Said Palin: “You don’t want to mess with moms who are rising up. If you thought pit bulls were tough, you don’t want to mess with mama grizzlies.”
As Salon noted, “These mama bears are the same hockey moms Palin targeted in her vice presidential bid, only now they’re angry.”
