HuffPost reports that Democrats flipped 549 state legislative seats, took control of 12 chambers, and now hold six new trifectas — 22 nationally to Republicans' 19 — their largest state-level gains since the 2010 GOP wave. Texas Democrats swept every statewide race and won the House for the first time since 2002, while Wisconsin flipped both chambers for the first time since 2010. DLCC spokesperson Will Rusche credits years of groundwork, and Democrats plan Medicaid expansion in Georgia and Texas plus repeal of Gov. Greg Abbott's school voucher plan.
