Obama focused on the "delegate math." He won the total delegate count in Texas, and he stayed close to Clinton on the delegate count in Ohio. "No matter what happens tonight," he said, "we have nearly the same delegate lead that we did this morning, and we are on our way to winning this nomination." In fact, March 4 was the first election day in which Clinton won more delegates than Obama (though the Florida and Michigan primaries would later be honored by seating half of the states' delegations). After winning contests in Wyoming and Mississippi the following week, Obama erased Clinton's March 4 gains. On March 15, he increased his lead by 10 delegates at the Iowa county conventions, when former supporters of withdrawn candidates switched their support to him.
