Last night's Democratic duel in Austin was a ratings winner for CNN. 7,576,00 total viewers watched the debate, making it the second most watched debate in cable history (behind the last CNN debate, from Los Angeles). In the A25-54 demo, the debate drew 2,986,000 viewers, also enough for second place on cable.

This means that CNN now has the top six debates on cable this season in total viewers, and the top seven in the demo.
