Politico today reports that Twitter will be offering the opportunity for political campaigns to run ads on it social network.

The article, “Twitter to launch political advertising” by Ben Smith, says Twitter has had five years of observing online behavior. Like Google with its ads, Twitter wishes to cash in on what should be a great money-maker.

As for the issue of disclosure, Smith spoke with Twitter’s government liaison Adam Sharp, who said disclosure statements probably are not legally necessary for their ads. But Twitter will offer the ability to show “paid for by” information via a mouse-over on the paid Tweet.

It will be interesting to see if any regulation springs from this new development.
