If Johnson can't herd the nutbags, that's not a failure because Johnson is a nutbag. Johnson won't cut a deal with the Democrats like McCarthy did. Johnson, like the rest of the nutbags, will crash the US government because that's the plan.
This isn’t about budgets. It’s about not fixing what is broken. Basically prior to Nixon, Congress authorized a maximum debt amount and the president was meant to spend it on programs that Congress wanted. Nixon decided he wouldn’t spend the money, which offended Congress and they changed how laws were written so that the president wouldn’t have a choice. Nobody ever removed the system of spending caps and here we are.
