Every time Republicans fuck with the government staying open, they lose support. They are way over their skis on this one and the solution is sitting on a tee for Biden.
Biden declares he is Constitutionally obligated to pay the debt by the 14th Amendment. Tell Yellen to pay our bills. Make the GQP sue to stop it.
Regardless of legal language twisting, the language "The validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned" reads pretty straight forward to the public. Even for Dems, who suck at messaging, this is an easy point to articulate and for the public to grasp. Bonus points that the same states that were the problem in the Civil War are still the fucking problem, because the 14th Amendment was specifically written to prevent these traitors from welching on debt and crashing the full faith and credit of the US government. History rhymes and all that...
If the already illegitimate Supreme Court forces a default, it will be very obvious the GQP is forcing it and they will own the following consequences. The subsequent crash will be hung clearly around their necks and they'll be annihilated in 2024. It will make sure everyone knows that the GQP has already packed the courts and that we must do something drastic about it if we want to keep our country.
If the Supremes backs the administration, one of the GQP's favorite manipulation tools will be declared unconstitutional.
TL:DR The GQP is bluffing. Stop negotiating with domestic terrorists and call their bluff.
