I've asked this question in a couple of different posts over the past week. Not one person has been able to spell out a scenario in which Hillary wins the nomination, be it by delegate math or some narrative of the campaign. 

I posted this week on a possible scenario in which Obama wins the nomination.  No one gave any prediction or idea for a Clinton nomination. 

The closest thing to someone telling me how Clinton will win the nomination is from a recent TPM reader's post that said that Obama should drop out if he doesn't win Texas and Ohio (because apparently it would be too humiliating to lose those states and stay in the race, even if you have the overall delegate and vote lead?).

For reasons that are obvious, Obama is not dropping out after Tuesday. So please, in all seriousness, can someone tell me how Hillary wins the nomination at this point?
