There's a lot of discussion here about whether or not Rove
really wants to run against Dean, and as a Princess Bride fan it's been great to see people mention the
Vizzini Gambit.
What I haven't seen anybody mention is the fact that Wesley survives not by avoiding the poison, but by changing the rules.
The point, not surprisingly, is that whoever runs against Bush should assume that they will be drinking poison. The key to winning in this case is not to expend a lot of energy trying to avoid the poison, but to figure out how to drink it safely.
