A lot more.
Thought to be the domain of the political left by some, social media has come to be nearly ubiquitous for both parties. One may even argue that the political right in the U.S. has passed the left. While not a perfect measure, one can look at the number of tweets sent by members of congress. From May 8th to June 8th, 2011, members of congress sent 15,383 tweets. The 232 Republicans sent 10,846 tweets (that’s about 47 tweets per member for this month). The 168 Democrats sent just 4,537 tweets (27 tweets per member). Republicans are tweeting almost twice as much.
