Funny, I read two accounts of the debate via yahoo. One starting off implying it was pretty uneventful, but then went on to talk at length about Walz's "gaffes" and in effect implied it was a win for Vance (while taking pains to point out he came across as perfectly normal and pleasant, and in no way weird, no, not weird at all). The other started off saying it was pretty much a wash but then went on to emphasise Vance's final 'weird' remarks.
The first was from The Telegraph (that is absolutely rabid and unashamed about its right-wing pro-Trump bias) the latter from the Independent (that I see as centrist, but many probably see as left leaning).
If viewers of Tuesday night’s vice presidential debate were expecting fireworks, they were sorely disappointed.

ANALYSIS: There may not have been a knockout blow in the vice presidential debate, but Vance’s answer to the last question couldn’t have been more revealing, writes Andrew Feinberg

Judging from that and what's been said here, I'm assuming it was indeed pretty much a wash.
