You will find, I hope, that if Obama is the candidate in the general, people will be open and receptive to whatever you have to say.  Think of how his nomination will be perceived.  There will be some people who are very angry about it, but my best guess is that there will be a much greater exhale of air and the country is going to be behind this guy.  It won't be too difficult.  However, by that time, his policies will be even clearer.

I understand that we are not used to a candidate who is putting forth concepts rather than concretes, philosophy rather than platitudes.  

It stretches us.  It puts out of our comfort zones.  But, in so many ways, our concrete, materialistic, greedy, self-interested society may just sense what's best for it after all and your job won't be so hard.
