Politwoops, Sunlight’s project to track deleted tweets from U.S. politicians that was recently named one of TIME Magazine’s 50 Best Websites of 2012, is getting a big refresh and expansion today. You’ll immediately notice the beautiful new design, but once you start using the site the addition of powerful filtering options and vastly expanded list of accounts will become obvious.

The sorting features are now front and center allowing users to quickly filter the hundreds of politicians by state, party affiliation and position. Curious about Republican representatives in California? That’s found easily in a few clicks. We reworked the structure of the site to improve reliability and provide more tweets faster. As one of the Politwoops moderators, I am enormously grateful to our developers for all the improvements they did behind the scenes.

Politicians now have individual pages with tabs to link their official, campaign and personal twitter accounts in one place. We nearly doubled the accounts we’re following to include over 750 accounts, but we need your help to expand that list to cover non-incumbent Senate and House challengers. The overhaul now allows us to easily add new accounts so please email us with anyone we’re missing and include their Name, State, Political Party, Office they hold or are seeking and, of course, Twitter handle.

We hope you enjoy the revamped site and thank you in advance for your feedback.

Update: Kaitlin wrote about the technical background of the Politwoops update and how the code is now open-sourced on the Sunlight Labs blog.
