Ah, transparency. The Sunlight Foundation put together Politwoops last year to highlight tweets that elected officials deleted. Mostly it‘s innocuous stuff, but sometimes some real gems come through. For example, the account of Rep. Mike Rogers, who is the main Representative behind CISPA, retweeted but then deleted a MapLight tweet about how the House Intelligence Committee, which Rogers chairs, „received 15 times more from pro-CISPA groups than anti-CISPA orgs.“ You can see MapLight‘s data here.
