Well, that WOULD prevent it ever getting out of the Senate, except being Dems they'd pull some crooked bullshit like voting to 'Deem it passed' without actually voting the bill.
But if our pocket Stalinists want to go that way with it, realistically it probably makes even more sense to say nobody under 30 should be allowed to vote on it, since so few of them have a honest, permanent buy-in with the real economy.
