A day before the latest all-important primaries, in Ohio and Texas (and oh, Vermont and Rhode Island), the expectation game has taken on even more significance than usual. Weeks ago, the pundits were saying Clinton needed a blowout win; Bill Clinton admitted they needed to take both Ohio and Texas. With the polls showing a tightening race, people are beginning to wonder what Clinton will do if tomorrow's results are muddled — which, given Texas' ridiculously complex primary-caucus hybrid, is a very real possibility.
