Both Democratic presidential candidates on Monday downplayed expectations ahead of Tuesday’s critical mega-primary vote spanning 22 states, which could decide whether Hillary Clinton returns to the frontrunner status she enjoyed for most of last year or whether Barack Obama will continue his breathtaking surge.

The vote, which will choose 1,700 Democratic delegates, is unlikely to decide the race, since the winning candidate needs 2,025 to secure the nomination. Both were looking ahead to the next set of primaries, including the critical votes in Ohio and Texas next month.
