An analysis reported on by Roll Call finds that Republican lawmakers on Capitol Hill use Twitter more effectively than do their Democratic counterparts:

Though lawmakers on both sides of the aisle have embraced social networking as a way to communicate with their constituents, Republicans might be doing it better.

A 20-page report released late last week by Edelman Digital, the new-media arm of the global public relations firm, shows that Republican Members on Capitol Hill are outpacing their Democratic counterparts in the world of Twitter.

Studying 456 Congressional Twitter accounts, the firm found that Republicans are exceeding on all the “success metrics”: engagement, mentions, amplification and follower growth.

Congressional Republicans on Twitter have their tweets replied to twice as often as Democrats and are mentioned more often.

Republicans also had an edge in analyses done through TweetLevel, a tool built by Edelman to score levels of “influence,” “engagement,” “popularity” and “trust” on Twitter — though liberal Independent Sen. Bernie Sanders of Vermont, who caucuses with Democrats, had the highest ratings for “influence” and “engagement.”

At the North Carolina level, my anecdotal experience has been that liberals dominant the #ncga and #ncpol hashtags on Twitter. Not necessarily lawmakers, but activists and citizens.
