Besides tying up their resources, it is possible that if we properly remarket our image we COULD actually start pulling greater support. Yeah, maybe you don't win this year. Or the next. But then something strange happens a little down the road... you start actually competing.
I do maintain we'll have to refocus our image first. We'll never win if they can just pick us off with name-calling and hot button topics. We win on the big picture, but that's hard to communicate.
Still... look at how America works. I mean, these third party candidates actually still get out there and try. They know they're hopeless, but they put up a fight and make inroads. What percentage of the vote did some of these guys get? How many spots did they pick up? Not many, but we are more aware of them. Occassionally, it pays off for them. Either way, they still keep coming back.
I guess if there is someone willing to give it a try, knowing the odds, we should give them the resources to help us out. Like you said, you never can tell!
