Well, what I meant is "I think it closes before the semicolon".

It looks like in the article Cael is quoting that references Sunstein's paper, the paren is in fact unclosed. In Sunstein's actual paper, it says "likely to shift more - a point that bears..." Similarly, the second parenthetical comment is also set off by a dash in the original. Tsk.

Er, I got kind of yak shaving there. :)
