This is mostly just a liberal wet dream scenario that exaggerates how loyal the R base is to Trump to portray them as a mindless cult. If they’re not "loyal" enough to him to actually nominate him in a primary, he’s not getting "upwards of 20-25%" (or even close to 10%, for that matter) in a GE. Even getting 3% could be significant, however, so it would certainly help Biden, but not nearly to the extent that some Democrats here think.
In this scenario - it’s very unlikely, yes - Trump would win a lot more than 3% of the vote. 25-30% is nonsense parody, and 10% is likely a stretch too, but 6-8% doesn’t sound like an unreasonable guesstimate.
Yeah, probably around 6-8%. 3% is ridiculously low. Gary Johnson beat that in 2016 despite running a meme campaign. A former sitting President with a small but committed base grieving against the “establishment” denying him the nomination would produce much more than 3%. 10% would be his ceiling though.
