The whole 50-state strategy sounds nice, but come'on, it is unrealistic. In Presidential elections, you only really go after 15 states, and you are out of money. We do not have the money to strongly back a Senate candidate in Alabama. Sorry.
If the local parties do a good job, hurray for them, but the national party really doesn't have the resources to compete everywhere. And face it, we are just wasting our time in some states, if the money could be used elsewhere.
It doesn't mean that you give full resources to every State.
Sometimes you get lucky where you were sure you were going to lose. We almost won the Kentucky Senate race. The fact that it was close was a shocker. More money spent on that race, and we would have surely won.
What race would that money have come out of?
The Democrats should've put their money into SC, NC, CO, AK, SD, KY, and FL.
They should have put their campaigners (Clinton, Gore, etc) into PA big time.
