The name of the couple you voted for is in italics. For me, Chip & Kim are in italics.
The case for Chip & Kim winning:
a) A nice couple winning the race might offset the past two whiny and/or hyper-competitive couples.
b) Unfavourable editing to Colin & Christie (though Flo is also an exhibit A against this defence)
c) Their toughest competition starts in last place with no money
The case against Chip & Kim winning:
a) Colin & Christie have raced extremely strongly in the past
b) Ever since I've started to watch the race (season three) my favourite couple has ALWAYS come in second (Teri & Ian, Jon & Kelly)
c) God wants Brandon and Nicole to win.
It's a tough call, but I've been rooting for them since the "you mean there was a route marker before the roulette wheel" days. Ya gotta have faith.
