Hmm, National City's stock downturn seems to have started in July 2007. I do remember in August, there was an article in our local paper saying how National City is no longer accepting applications for equity loans.
Fortune just posted that National City is looking for buyers as Ducky mentioned. Two likely candidates are Key and Fifth/Third, but if they can't stabilize their financials, any acquisition may be unlikely.
Shucks, National City's Every Rewards Visa is on my list. Darn it, I still want that rewards card...
