I’m not going to sit here and claim that Sanders favors a balanced budget. He doesn’t, and he’s not going to if elected.
But: massive deficits have been a thing for several presidential terms now. Both Republican and Democrat.
Some trace our massive budget deficits back to Reagan, but George W. Bush really took the brakes off with those unnecessary forever wars, tax cuts, Medicare Part D, etc. etc.
Obama and Trump haven’t really done anything to reign it in, either.
Fiscal responsibility is out the window, basically. The GOP has had several chances to prioritize it, and they didn’t.
In ‘16 y’all nominated Trump, not Rand Paul or some other true fiscal conservative, and since then Paul Ryan has been unceremoniously tossed, so don’t come crying to me about this.
