TULSA, Okla. - The omens started early Saturday morning, before the gates to the "Great American Comeback" rally were opened. I got downtown later than I'd wanted to, making a detour to buy a poncho, after weather forecasts suggested a chance of rain. Shortly after 9 a.m., I started looking for parking, and two Tulsans who were charging $30 for a space politely said I might want to drive around before paying.
