Senator John McCain of Arizona has the most followers by far -- more than 106,000 -- cashing in on his name recognition as the Republican presidential nominee rather than his Twitter proficiency.
The 72-year-old McCain is an infrequent Twitterer and acknowledges getting a little assistance. "YEs!! I am twittering on my blackberry but not without a little help!" read one recent message. [...]
For Mark McKinnon, a one-time media adviser to former president George W. Bush and Senator McCain, the discovery of Twitter by Congress is a sign it may no longer be cutting edge.
"If members of Congress are Twittering, we can be fairly certain it won?t be hip much longer," he wrote in a blog post on The Daily Beast website.
