Do you honestly know anyone who (a) doesn't already know for whom they will vote for president and (b) is likely to vote in November? My guess is that you don't know anyone who meets both criteria. I know I don't.
In the next 100 days the two parties and their two candidates will spend many millions to sway that tiny fraction of true undecideds who care enough to vote. And they only care about the undecideds in 12 so-called "battleground states," states which really could go either way.
In the other 38 states our votes for president are essentially cyphers. Yep, if you are an undecided who lives in either California or Utah, forget it - nobody cares how you vote. California will go Democrat and Utah will go Republican, regardless of what you decide to do.
The only states whose voters are courted are those teetering on the knife's edge. The good part is that in the other 38 states we don't get overwhelmed by Obama and Romney ads. The two parties already know which of them will get those states' delegates to the electoral college.
