Then

And I concluded: “Even if we think no leader could heal this party, Labour still needs a leader. It’s an effort to support someone on those terms … but [there was a familiar adage here that I’m a bit sheepish about] vote like you’ve never been catastrophically disappointed.” So that’s the first thing that was wrong with it: to explicitly say Smith [Jeremy Corbyn’s Labour leadership challenger ] didn’t have enough to recommend him then recommend him anyway, in some mad leap of faith, was lame. (The Guardian.)

Does "then" mean "at that time" or "therefore" in the passage above?
