Good post and I agree completely. The problem, as you stated, is that most (on both sides) see Roe v Wade as the only think keeping abortion legal. It is highly doubtful that abortion would be illegal in many of the solid blue states even if Roe was overturned.
A person in a state that prohibits abortion could easily just drive to a state that does allow them.
The Feds, however, could attempt to pass legislation to ban abortion.
The political consensus in DC would never lead to a federal law banning first trimester abortion for adult women. This partial birth thing is a whole different ball of wax - especially when viability can be scientifically demonstrated at 20+ weeks.
The States is where this belongs, for many reasons. The country is too divided to have a uniform abortion law (again, we’re talking about adult women before 20 weeks). Let the States have a crack at it, let’s see what political consensus they can hold for State based bans. Send it to the States, and this will also free the national Republican party from the litmus test on this issue, so we can focus on other issues regarding government.
