Would you consider that a success?
No. One can say anything after the fact. Many do. It requires nothing. In sales I have heard many times sleazy salesmen come in to my customer *after* I've done an order and say, gee I could have done it for 25% less. Hell, they could do it for 75% less if they don't actually have to do it.
I don't tend to talk to 60+ year old liberals. These are Gen-X types. They never had the opportunity to vote for Goldwater.
The thing is, it can be done. People can be swayed. But as in sales, one has to ask for the sale and actually deliver. Otherwise the sleazeball gets in.
The point being that most Obama voters are open to an alternative. The messaging has to be correct to reach them, however. If they'd be willing to vote for a Barry Goldwater, then that opens a lot of possibilities.
