For Hillary the minimum she needs to do to credibly carry on is to triumph in Ohio, where she currently leads in the poll, and the popular vote in Texas, where she trails narrowly according to the latest numbers. If she loses delegate-wise in Texas because of the caucus element having won the ballot earlier in the day, she’ll be able to argue that caucuses--which have given Obama a string of victories--unfairly disenfranchise her supporters who can not afford to take an hour out of their day to participate in these events.
Tomorrow, Clinton and Obama go head to head in Texas with both stumping across the state in an attempt to gain a last minute advantage. Hilary has conceded that she has to win here. It is telling, though, that she plans to be in Ohio not Texas on election night.
