I was always going to vote for McCain. What this speech did was transform a tactical vote (to keep Obama out) into a strategic one (to position Palin for her own Presidential campaign in 2012 or ‘16).
How about Sarah Palin and Bobby Jindal? That will cast fear in their hearts for years.
Our biggest threat now is Democrat election fraud. They have been seeding the voter rolls for year with phony names and they will again this year. That adds up to a lot of votes over time.
