This will probably motivate the younger folks that were going to pass on the election to turn out, in some states this will have the effect of making the Dims completive where they would not have been this election cycle.
Long term this is probably bad news for the GOP, for the past 50 years Roe has motivated social conservatives to turn out and given the GOP a electoral advantage. I suspect many of those same folks will figure their work is done and will slowly drift away from political activism.
On the left this will likely motivate the younger generation to become politically active, I would not be surprised in 20-25 years to see the majority of states have legalized abortion.
The young will determine the fate of abortion
Younger voters are more pro-life than their elders.
