Cook Political shifts seven legislative chambers in Democrats' direction.
In the key midwestern battleground of Michigan, a surge by presumptive Democratic presidential nominee Joe Biden leads us to shift the state House – the only chamber being contested in the state this cycle – from Lean Republican to Toss Up. We're also shifting towards the Democrats three chambers in southern presidential battleground states where Biden is running tight with Trump. In North Carolina, we're shifting the House from Likely Republican to Lean Republican, where it joins the state Senate, which had already been in the Lean Republican category. In Georgia, we're shifting both chambers from Likely Republican to Lean Republican. As a precaution, we're shifting both chambers in Ohio from Solid Republican to Likely Republican, following the arrest of the Republican House speaker. Finally, we're moving the Connecticut House and Senate, both currently controlled by the Democrats, from Likely Democratic to Solid Democratic.
