"House Republicans demonstrate an unmatched ability to connect with the American people in the Internet's most popular communities," House Minority Leader John Boehner boasted in a news release in January.
Congressional Republicans do have more members registered on Twitter and have more Twitter followers than their Democratic counterparts, according to the site TweetCongress.org, which tracks the data.
Republicans are also the more active Tweeters, with Senate Republicans' Twitter handle "Senate_GOPs" averaging eight tweets per day.
"This is just one-upmanship," Minnesota professor LaMarre said of the GOP dominance since 2008. "It's political strategy. [The parties] are learning from each other in the social media space."
