CHARLOTTE -- There's a new speech-maker being heralded at the White House and her name is Michelle Obama.
The first lady opened the Democratic National Convention on Tuesday night with the message that President Obama understands the middle class and their concerns better than his Republican rival Mitt Romney.
By the time Michelle Obama finished telling stories of the couple's own struggles with money and their shared dreams for their daughters, Twitter had exploded.
According to the online social networking service, there were 28,003 tweets per minute at the conclusion of Obama's remarks. That's about double the number after Romney's acceptance speech last week, which was 14,289 tweets per minute at its peak.
"She was stunningly powerful, straight from the heart," tweeted actress Ashley Judd, who is a Tennessee delegate to the convention. Judd said Obama was "breathtaking" and that the first lady's remarks left her "rather speechless."
