I firmly disagree with you here: the debt will be pegged on Obama (to the extent that American voters actually care about the debt at all).
Even though we non-idiots all know that it was Bush that effectively incurred all of the debt of the GFC, the majority of Americans will still hear "Obama incurred 2x more debt than the 43 presidents before him combined" and a solid 1/3 of the country will nod along (and probably another 1/3 will kind of think that's true but will defend Obama anyways). They'll then say that the Republicans' added debt was a fraction of Obama's added debt and that it was necessary to mitigate a lagging Obama economy.
I hope you're right, but I see the Republicans continuing to get away with their theft and continuing to pivot and blame it on Democrats, immigrants, minorities, etc.
