Again, you ignore the actual realities of politics. Obama promised to codify Roe v Wade his first day in office. He then refused to, since it was better for democrats to keep it on as a political bargaining chip.

Now, what are US liberals supposed to do? Not vote and lose? Vote for the Republicans and see abortion criminalized federally? No, they have to vote for the Democrats again and maybe hope they finally try to pass their agenda. There is a false choice presented. It was urgent to the voters, but not to the politicians.
