There has been no election since at least 1928 that the country was better off because the Democrat lost.
And I say 1928 not because the Republican was better (Al Smith was actually the first time in a while where the Democrat was clearly leagues better), but simply because it was probably necessary for Hoover to f—k up and take all the blame for the Depression for FDR to come in and save the nation.
Given hindsight wouldn’t you say 1976 was a bad election for democrats to lose win given what happened in 1980(not only presidential but congress too) and 2004 was good that you lost as well given the 2006 and 2008 landslides vs the possibility of Romney/McCain getting in 2009 with filibuster proof of senate
Fixed that for ya. 1976 was the one election the Democrats won that I wish they lost for the reasons that you said as well as the fact that Ford would've handled (even if only slightly) the late 70s better than Carter did, and I'm also glad we lost in 2004, again, for the reasons you listed here.
As for the election the Democrats lost that had no silver lining to said loss, it was 2000. Gore would've handled 9/11 (if it even still happens) worlds better than Bush did, there'd be no invasion of Iraq, no Bush Tax cuts, we'd have gotten the ball rolling on Climate Change, and there'd be a far less severe financial crisis in the late 2000s, and that's even if Gore ends up a one term President. Don't get me wrong, 2016 was a bad loss, especially with hindsight given the events of the last year, but even that election loss had some silver linings (Dems retaking the house in 2018, GOP gerrymandering post 2020 not being nearly as bad as it could've been, Trump accelerating Suburban trends to the Democrats).
