The Politico notes that Twitter may become a key political weapon in the next election cycle.

Indeed, the robocalls that dominated the past two election cycles could become robotweets in 2010. Rep. Judy Biggert (R-Ill.), for example, bypassed the local media recently and used Twitter as a direct response to a robocall that criticized her on troop pay raises.

Lawmakers who tweet say their colleagues are missing out.
