Big spenders can point to visible progress to help them at the next election, and to hell with the next generation. That was also the impeachment issue. Ignore violations of law and get away with it, so long as the polls last. The ends justify the means. First, our congressional delegation may try to get us the next five years' federal gas tax funding early, saving all those loan costs.
Debt blocks a response to changed conditions.
Steal from the future to avoid hard choices today. Repayment depends on speculation as to how much gas tax money we get from the federal government. If a recession comes, if Congress diverts the funds, someone gets burned. To back Bigger Government, the Democrats are saving Bill's bacon, even though debt restricts future discretionary spending just as much as permanent tax cuts. A plague on both your houses.
