Nevada: Romney won by a lot. Ron Paul came in second! It's not much more decisive than Romney winning Wyoming, however, because hardly anyone showed up to the caucuses. At least, that's my opinion. The Republican Party still appears confused.
As for the Democrats, Clinton is in the lead. I'm really not sure why the recent Clinton camp shenanigans haven't turned voters completely off toward Hillary. I mean, really, I don't consider Obama to be the nice guy either (considering his tactics in Illinois elections), but something is definitely going on with the Clinton campaign. Ever since that one time Obama did better than Hillary it's been scary. Doesn't this jog a few memories of the last Clinton White House? Why do we want that again?
South Carolina: This was a much more decisive victory for McCain. Still not sure if that makes him the front runner. It probably puts him equal with Romney. As for Ron Paul, he came in ahead of Giuliani, at least.
On the Democrats side we will not find out until Jan. 26th because they have a different primary date for each party.
