While I agree that I think it is better to sink Billary right now while she's on the brink the fact remains that even if she wins Ohio and Texas (I doubt it) she would have a minimal delegate gain due to the Dems proportional distribution. Texas is a little more complicated but the fact remains that Obama would still be in the lead for overall committed delegates. This "I won this state" is really just bragging rights.
At the same time for Hillary to claim the bragging rights of a state win then she has to acknowledge that Obama has the same bragging rights for his states won. Throw in a delegate lead and 11-straight wins and Hillary has no rationale to say she has the Mo.
“...even if she wins Ohio and Texas (I doubt it) she would have a minimal delegate gain due to the Dems proportional distribution.”
Delegate count after Ohio and Tx doesn’t matter. It will prove he cannot win the big states and the Clinton’s will have leverage to runoff in Mich/Florida, that will give her the lead. Game over. It gives the SuperDelegates cover to abandon the great black hope.
