Yea. I'm not from the US (so an outsider's and probably naive perspective) ...
but the whole Biden thing seems off. Trump is a known quantity. The point of his running, at a basic level and besides vengeance, is to try the MAGA thing again without COVID "interfering". Also, if you think back to the 2020 Dem primaries, where no one was really happy with any candidate and many were asking of the Dems "is that the best you've got" ... a Trump sequel is kinda republicans forcing that question again.
As for all of the attention ... well there's a lot on the line here: Trump's a known quantity ... so, Dems, how you going to defeat him this time? Because ... if you lose to Trump, twice, both times by standing by a party elder ... that's maybe "shame on you". Moreover, we all knew Biden was old. A single term was sorta, kinda part of the deal because of that (remember, he wasn't doing well in the primaries, he never has really). So, has a bargain been broken here? A gamble lost? A mistake, perhaps all the way back in 2020 but certainly behind the decision to run again, come to fruition?
Beyond all of that ... I thought excessive media attention on Trump and the free publicity he gets was a bad thing (he's probably jealous about Biden's media attention lol)?
