Tweet your Senator on Health care Reform

Tweet your Senator is a Google Maps Mashup which plots your Tweet on Google Maps. This mashup a feature of BarackObama.com was launched in late July. (via Mashable)

To use it, you enter your zip code and the mashup will create a pre-populated tweet which is targeted for a Senator from your State. Even though the pre-poulated tweet is pro Health Care Reform you can edit it and express your opinion either way, just leave the hash-tags alone though.
