I tried to search for the answer, but the search engines automatically assume that I am an idiot that actually meant “Red to Blue” and give me the wrong info.
Only 1 house seat flipped Blue to Red so far. No Senators or Governors.
@Czarcasm, I moved this to Politics & Elections from Great Debates.
I actually meant to put it there, but hit the wrong button. Thank you.
P.S. I think you one-upped The Grapist! 
Basically the answer is no. The Republicans did {not} flip any state legislatures or governorships. They lost ground everywhere.
You can find a nice summary here: 2026 State Legislative Elections: The Results and What...
ETA: I assume you meant state-level House and Senate, not federal House and Senate.
Actually, either.
I believe the Texas 32nd District is the only one the GOP managed to flip.
Republicans flipped the governorship of Guam, which is across the International Date Line so the votes were already counted by Tuesday morning (in the mainland US). This led to a lot of gloating posts on social media about how the red wave was coming, which now serve as renewable sources of schadenfreude.
(Actually, their non-voting Congressional delegate flipped from R to D at the same election, so it wasn’t even a great election for them in Guam)
So…by flipping early, Guam may have influenced Republican voters to stay home because they thought the right-wing votes were in the bag?
Behold the age of the Mustardist! (Who is not Mean Mr. Mustard, surface resemblance aside.)
Maine 2 might also flip, but it’s not there yet. It’s one of those schizophrenic districts that has voted for Trump three elections in a row, while voting in a Democratic representative since 2018. But Jared Golden was a pretty conservative Manchin-like Democrat. He had worked for Collins and was a leader of the Blue Dogs. Moreover he endorsed the incumbent Republican candidate in NY’s 17th (he lost) and muttered about not being particularly impressed by either candidate for his own former seat. That the race is even close is probably a testament to the blue wave.
Bad place to leave out a “not”.
Ack! Of course, did not flip any.
There was a sort of Red-to-Red “flip” in the Nebraska Senate race! 
The incumbent GOPster won against Dan Osborn, who was running as an Independent. Some analysts think the Blue Tsunami would have given Osborn victory had he ran as a Democrat or even if he had announced he would caucus with the Democrats if elected. He IS a “progressive” and WOULD have caucused with the Dems, but feared that “Democrat” was still a dirty word in Nebraska.
Some right-wingers boasted that Guam was voting red, based on… something, early info, exit polls, or lies. That may have gotten more attention than the actual result.
Wasn’t that one of the districts that were gerrymandered?
I believe so, and possibly the only one where gerrymandering actually worked out in their favor.
I lived on Guam in the early 90s and went through an election season there. From what I remember, politics was solely about the people involved and had little-to-nothing to do with party. And there were dynasties of different families as well, so feuds went back generations.
30+ years later, maybe it’s not like that anymore, but I have a feeling things haven’t changed that much. It’s still small and remote, and I’m sure its politics are as insular as they ever were. I would never count on election results there being any indicator of anything for the rest of the country.
Last I heard, Kansas has still not called the Governor’s race. Incumbent Laura Kelley (D) was term limited. Cindy Holscher (D) is currently ahead of Ty Masterson (R) by a couple thousand votes (and in fact declared victory Wednesday afternoon, even though they’re still counting and he has not conceded). Kansas allows mail-in ballots to be received and counted up to three days after election day as long as the postmark is election day or earlier. So if Masterson manages to pull out a win (which doesn’t seem likely at this point) that would flip a governorship from D to R.
No rational person would but, we are talking about el donald’s cult.
I saw that this morning on the AP results page and just checked again. There are two now, TN-9 and TX-32. Don’t know what the story is on those.
