The wind is in our sails recently with a series of excellent bills passing all at once at practically the last possible moment, including the new "Inflation Reduction Act" (which really doesn't have much to do with inflation) that's on the verge of passing which will include major climate action. The issue for the midterms will be the difficult uphill push of keeping control of not just the Senate that you mention here (I think it's likely we will keep hold of the Senate), but more crucially the House of Representatives, the other legislative body of our government. Traditionally, the party in power almost always loses seats and often control of either one of both arms of government in an American midterm election due to voter discontent or malaise, poor decisions, voter apathy about midterms vs. general presidential elections, whatever. It's fairly rare to retain control of both in a midterm. And the Democrats have had a very, very rough year which has left many unhappy.
We're on a hot streak these last few weeks unexpectedly bc of these new bills, and because the public is increasingly galvanized to action and outrage by the Republican Supreme Court striking down Roe v. Wade and abortion rights. This may all help us, and so might the very good new jobs report today which confirms we are not in a recession. But keeping control of both the Senate and the House will still be an uphill battle, especially with election-rigging gerrymandering and corruption by Republicans in many states. I think it is possible to hold our majority, but I am not counting on it and I think it will be a hard fight. We have a better chance now than we did a few weeks ago, that's for sure.
