Politweets by Whole Whale lets you create a free Twitter advocacy widget for your website to help your supporters identify their U.S. Representative by zip code and tweet them your custom messages. Reach decision-makers where they are and get your issue to the top of their political agenda.
Nonprofits needs access to more tools like this. Super cool
Pros:Easy to set up, potential for wide reach of relevant political officials
Cons:Tweet creation process could be more intuitive
I like this as an alternative to a "thunderclap," since Politweets is designed to get the attention of members of congress instead of simply get a bunch of users to tweet the same message at the same time.
Pros:super easy to use customizable
Cons:none that i can think of
