Bless his heart is a gentle way of showing pity or condescension, especially down South. Example:
That Bobby looks like he was beaten with an ugly stick. Bless his heart.
Sheila is so fat, you can show a movie on her butt. Bless her heart.
In his remarks in Iowa, Romney wrapped his insult in a veneer of mock-compassion. This resulted in last week's hash tag #BlessObamasHeart on Twitter.
I course, I got in on the fun:
Obama thought that he would come across as cool and exotic to Americans if he bragged about EATING DOG FLESH. #BlessObamasHeart.
He is SO modest. He ordered his college records sealed. I guess that he didn't want to show off his amazing GPA. #BlessObamasHeart
He's killed Keystone, the coal industry, harassed the private sector, unleashed his czars, his regulators, and the Employment Prevention Agency, and yet the unemployment rate remains high. #BlessObamasHeart.
That poor lamb knows absolutely NOTHING about the real world. Everything Obama knows he learned in some college faculty lounge....and from his communist mentor. #BlessObamasHeart
I am so glad that Barry slept through all those hate-filled rants of the Reverend Jeremiah Wright. That maniac would have been a bad influence. #BlessObamasHeart.
Barack Obama needs that teleprompter to keep his foot out of his mouth. #BlessObamasHeart
While the gang from Chicago flails away angrily, filling the air with mean-spirited attacks and lies, Romney is making fun of these playground bullies. While Obama appears more desperate, the former Massachusetts Governor appears more Presidential.
