Democrats have not taken control of all these blue states by the will of the voters. No, it has all been done by a few powerful democrats. And once a state has been turned solidly blue in governance, they move on to the next state. For instance, they perfected the steal in California, then moved to Oregon, Washington State, Nevada, etc, etc. They then did the same in the northeast, in the states surrounding DC, before moving on to the southeast where they made quite a bit of progress before actual conservatives took a stand and starting moving states back into the red column.
I believe Lee Zeldin actually won the Governor's race in 2022. There was just the amount of fraud needed to push Hochel over the line. Where was the GOP? They were busy ousting George Santos for a few (well more than a few) exaggerations on his resume. Meanwhile, Robert Menendez of gold bar fame, is still to this day a Senator.
“but where is the help from GOP leadership?”
The Stupid Party wants to be liked more than they want to win.
