Sophistry. You are definitely splitting hairs if you are trying to argue that.
If you want, entitlements + SS are the biggest group of items on the budget.
Regardless, I'm totally fine with across-the-board cuts to everything, in the interest of avoiding seriously bad shit down the line.
Edit: Also, unless the pledge has legal power (it doesn't,) it doesn't violate the constitution. A senator or congressman can jaw and sign private, unenforceable agreements all they want, if they don't have the force of law then they have no legal standing, and if they have no legal standing then its not a violation of the constitution since they can just change their minds at any time.
Stop being dumb.
