On some of the major issues I was for Donald but I voted for Hillary because she appeared less crazy. Now you have the worse possible crisis scenario and he is blowing up.
For me, the few major issues on which I thought Trump sounded reasonable or at least had a valid point can be categorized as:
1) centrist fluff that he didn't have any intention of keeping (having a better Obamacare alternative; undertaking massive infrastructure projects, etc)
or
2) where Trump proposed an alternative to longterm bad (largely bipartisan) policies, but then he demagogued it all to hell and handled it badly. The latter includes taking a tougher trade policy with China -- but the Trump Trade War approach, necessitating massive continuing farmer bailouts, was sloppy grandstanding and not productive. I do support restricting Huawei.
There's also the immigration issue. I think the Dems are rather cynical trying to increase immigration as much as possible in order to add new voters and turn some more states blue, without looking at assimilation and how rapid large-scale immigration effects the US. One very negative impact is the ascendancy of racist and white supremacist groups. Another is how it further marginalizes poor people and minorities. And keeps down wages. Any time the US has undergone large-scale immigration, there has been a nativist reactionary backlash, resulting in immigration being usually reduced for decades. And it is easier to assimilate white Christians, say Eastern Europeans, than Somalis or Bangladeshis. I like the diversity in America, and the US is still able to skim off the best and brightest from poorer countries (I think I saw that 1/3 of US doctors were foreign born!). Of course, Trump has zero nuance, and ginned immigration up into a big racial thing, while pretending Mexico would pay for a border wall.
And lastly, Trump presented himself as less hawkish than Hillary. He wanted to pull back from US involvement in foreign conflicts. Not that he has done much about it really. Of course, Trump counters that by upping the Defense budget by $300B (a waste of money which makes a future war more likely), and cozying up to belligerent states such as Russia and Saudi Arabia (gotta make that $8B arms sale, so the Sauds can continue to obliterate poor Yemenis).
So there's very little that Trump has done that I support. But he ran the 1st time as a moderate Republican and as the candidate of change. Neither approach is really open to him this go round. And with the economy a mess, his only real approach is to burn Biden to the ground. I expect we'll be hearing plenty of Lock Him Up chants.
Obviously, it would have been much better having Hillary in charge of handling the virus. Hell, if Trump was smart, he would have brought Hillary in on March 1st (or Feb 1) as the virus czar. She's competent and if things go badly, it's a Dem to blame. If things work out well, all credit to the Great Bipartisan Trumpmeister.
[obviously that was never happening; but the Dems always go weak-kneed and put Repubs in charge of Defense or some such]
