Ann Romney joined Twitter last night, apparently to retaliate against CNN talking head Hilary Rosen, who criticized Ann by saying she "never worked a day in her life." @AnnDRomney has tweeted twice so far:

Pugnacious with a hint of mommy rage: a promising (albeit brief) debut for a Twitter kerfuffle novice.

Welcome to Twitter, Ann. May your zingers be swift as the prancing horses in your stable.

Update: Fox News is making hay from Ann's kerfuffle. What an amazing family portrait. I keep thinking it'll turn into a Magic Eye image if I stare at the gingham long enough. [@AnnDRomney, ABCNews, image via Getty]
