On the one hand, paying down a debt to stave off mental anguish might be worth it to you. The most important thing about allocating your money is doing what brings you the most happiness, and if that means reducing stress through a reduction of debt because you feel uneasy about politics, than that's what you should do. I don't know where you work, but if it involves government contracts, you probably should realistically assess whether it will be available for 6 years or not.
But know that it's more likely an entirely self-inflicted and unnecessary stress. Without comment on whether the political or economic climate is such that we are in danger or not for the next few years, it's always helpful to keep in mind two things:
(1) It's never as bad as the "other party" thinks it is, and you're investing for decades, not one presidential or congressional term. An economic recession will not mean you definitely lose your job (most of us don't) and it will not mean your retirement saving strategy has failed. We will recover.
(2) The impact that your own actions have on your savings are far greater - orders of magnitude greater - than the impact of any political decisions at any level of government. Sure, local taxes will go up sometimes and cost you $1,000 extra, and sometimes a tax shelter will lose a ceiling tile and cause a bit more drag on your account. But those changes are tiny compared to your own choices about where to put the money you earn. No matter what you think a politician might do, it's almost certainly not worth making a bad financial decision like paying down a 1.5% interest mortgage (random number) instead of filling a tax-advantaged account for tax savings and tax-free earnings at a likely higher rate!
