As is traditional, the Republicans drafted a law, got bipartisan support to push it through congress, and then after it passed publicly flip flopped their support for the law they just wrote when they realized they could score political points by complaining about it while the Democrats would hold to their agreed support.

This way the Republicans get the law they want, get to claim any benefits of said law by pointing to their voting record, and get to blame anything people don’t like about it on Democrats, all at the same time.

Meanwhile there are no consequences to their bad faith actions because the Democrats will just bend over and take it in the name of bipartisanship and working across the aisle because half of them are Republicans, they just don’t want to call themselves Republicans and leadership is willing to fight tooth and nail to protect said members.
