I'd settle for social democracy, I think most members would, but not the third way, that poisoned the party, destroyed it in order to save it, but just ended up destroying it.
You can win elections by not being the government, because eventually all governments piss the electorate off, that's what New Labour did in 97, John Major was fucked and Blair looked fresh, modern and vaguely progressive
in reality John Smith, had he lived, would've won by a landslide in 97, my cat would've done!
New Labour then took that enormous goodwill and a stonking majority and pissed it away until there was nothing left, because, in the end, they stood for nothing but the status quo.
