The twitter logo.President Barack Obama’s speech last night at the Democratic National Convention set a new record for political moments on Twitter, according to the company. Right after the speech, 52,756 tweets per minute came in referencing @BarackObama and #DNC2012.

According to Twitter’s blog:

@barackobama delivered a great collection of tweetable lines this evening, and Twitter responded accordingly. His five top peaks in Tweets per minute were actually all higher than any other moment for a speaker in either convention. The moments in his speech that elicited the biggest Twitter reactions were:

-43,646: “I’m no longer just the candidate, I’m the President” -39,002: “I will never turn medicare into a voucher” -38,597: Discussing Medicare -37,694: “We don’t think government can solve all our problems…” -34,572: Quips about the Olympics and “Cold War mind warp”

More than 9.5 million tweets were sent relating to the convention in Charlotte, North Carolina, including about 4 million tweets on the last day–that’s about the number of total tweets referencing the entire Republican National Convention, according to Twitter.

Politico reports Twitter ran a political sentiment index about the conversations and found that tweets relating to both Obama’s speech and Mitt Romney’s speech at their respective conventions grew more negative after they finished. In contrast, tweets about former President Bill Clinton, Vice President Joe Biden and First Lady Michelle Obama grew more positive after they spoke.
