'we have won the argument'

[denem]

" ... we have won the argument and rewritten the terms of political debate. But I regret that we did not succeed in converting that into a parliamentary majority for change.

There is no doubt that our policies are popular ...The question is, how can we succeed in future where we didn’t this time?"

I am grateful beyond words, that I shall never have to hear something along those lines, the night of Tuesday, November 3rd.
