Sorry but that is incorrect. Even under the worst case scenarios “unfunded” mandates are nowhere near 400 Trillion. And “unfunded” is a misnomer as well, when speaking of things like SS etc.
The biggest treat to this nation is not “unfunded” mandates, it is a failed educational system. That is without question the biggest long term threat to the US. An ignorant electorate
Im sorry 210 trillion but that discounts SS and Medicare so yes closer to 300 trillion
