What concerns me is that the dems will find some pretext to run a primary challenger (Hillary??? - God help us) and then it could be some tough sledding for whoever we have on the slate. Is mine a genuine concern or is it too late for a dem primary challenger?
I think it's an extremely legitimate concern. Unless the dems plan widespread cheating at the polls (I'm sure they do) - Obama does not have a leg to run on. However, if they bring in a primary challenger - they can run on change again - and make it much tougher for us to win.
I think there's at least a 50% chance our nominee won't be running against Obama. As far as it being "too late" for a challenger - there are ways around that - if, for some reason Obama is unable to run. Don't put anything past them.
