What They Care About

How this is measured

Bubble size = how much of Katherine M. Clark's sponsored bills, cosponsorships, campaign statements and tweets go to each domain. Votes are left out because they follow committee seats; domains a member's committees handle are discounted a little. Anything from the last 6 months counts double, so a topic they are on about right now grows. Darker = they have broken with their own party more often on that topic: the share of party-line votes since 2009 where they voted against their party's majority (gray = fewer than 8 such votes). Based on 3 sponsored, 24 cosponsored, 16 statements, 110 topical tweets. Click a bubble to open what they support and the bills and tweets behind it; click it again to close.
