If it's possible to separate the person as a symbol from their politics, then yes, KH's achievement should be celebrated by all women. It's been a long time coming.
In terms of the politics, their victory is wafer thin at a state level. The republicans were highly motivated and mobilised a huge amount of extra voters. Ignore the popular vote, the electoral college is what counts.
The Dems have lost congressional seats this election. That's a massive fail. They have an uphill battle to try to get hold of the senate. Without both houses, they have really very limited powers. The race for the senate will start immediately, with 2 seats up for grabs by vote off in January, and then the main congressional and some senate seats up for grabs in 2022. A load of radical, women-hating policies will just turn floating voters back to the Republicans again, and they must know this. If they don't, then they will lose both houses in 2022, and it will be a lame duck administration until 2024. Being Vice President of an administration that failed before it even got going will not likely result in a KH presidential run in 2024. If the Dems don't recognise this, then they really have no political nouse, and don't deserve to be in power.
Just out of interest, what women's groups/lobby groups fighting against gender politics are prominent in the US?
