From a Marist poll (rated A by 538) released this morning, NPR reports:
"78% of Democrats say the court's decision makes them more likely to vote this fall, 24 points higher than Republicans....
"Democrats have regained the favor of voters to control Congress, with 48% saying they are more likely to vote for a Democratic candidate in the fall and 41% more likely to vote for a Republican. In April, Republicans led on that question in the poll 47% to 44%, which was within the margin of error."
But there's always a but: "However, the lead for Democrats may not translate into maintaining control due to the way voters are geographically distributed and how boundaries of congressional districts are drawn."
State-drawn boundaries have become so partisanly fixed, no longer do Democrats have 2006's 80 competitive districts to run in, which, by nominating moderate candidates, allowed the Dems to flip the House.
On 15 June, Cook Political Report released its assessment of competitive 2022 seats. Forty-five were ranked as "Lean Democratic," "Democratic Toss Up," "Republican Toss Up" and "Lean Republican." Of those, 10 were among the latter, leaving 35. But with a bit of luck, Democratic enthusiasm, smart Democratic campaigning and Republicans' Supreme Court, that number will grow.
