Sure, Trump didn't cause the pandemic, but neither did Biden and the inflation isn't unrelated to Trump's fiscal policy being looser than it needed to be even before the pandemic either, as well as being fundamentally the Fed's job to solve[2]. It's difficult[1] for an incumbent to win by attacking the track record of the last government especially when much of it was factors outside their control, but not impossible, especially since Trump has presented wavering voters with plenty of other reasons not to vote for him. Trump is living proof that excuses work...
[1]Not impossible though: an unpopular British government won a majority in 2014 by constantly blaming slow post recession growth on the other party's borrowing five years earlier
[2]You can absolutely guarantee that if Trump was in power the US would have experienced at least as much inflation, and he'd have wasted no time in blaming the Fed
Would have been more effective to remind people why they didn't vote for him than remind them of his behaviour afterwards which he's perfectly good at doing himself.
This is more or less the direction I was heading w/ my post. I don't think it's a messaging issue per se. Rather it's control of the messaging. The economy in general has been on a steady path for a while, despite ups & downs: it's trending towards a bimodal distribution where certain parties are doing quite well and others are doing less well. But what I've seen the last several election cycles is the indicators that dominate what I see on TV, read online, etc swap depending on who is in power. So my expectation is that literally nothing will change yet we'll be hearing about how awesome the economy is for everyone in several months.
