Nope, you’re spot on.
In partial defense of GWB, I believe a very large chunk of the debt he added was the bipartisan “stimulus” package that would keep us out of a severe recession.
Obama’s and the Democrats’ only criticism of that bill was that it wasn’t big enough.
Its falling under GWB’s responsibility is more a function of the calendar than G’s spending/borrowing proclivities.
BTW, who writes this crap? I puzzled over it for five minutes trying to figure out who had borrowed what.
