PRINCETON, NJ -- Gallup Poll Daily tracking conducted March 28-30 finds Barack Obama leading Hillary Clinton in national Democratic preferences for the nomination, 51% to 43%.
This is the fourth consecutive Gallup Poll Daily tracking report showing Obama with a statistically significant lead. It marks the first time since late February that either Clinton or Obama has sustained a statistically significant lead in the race for more than two consecutive days.

The current outlook for the general election in November, based on Gallup Poll Daily interviewing from March 26-30, shows a virtual tie between both Democratic hopefuls and the presumptive Republican nominee, John McCain.
McCain is ahead in both hypothetical ballots, but by only two percentage points against Clinton 47% to 45%, and by just one point against Obama, 46% to 45%. Neither of these leads for McCain is statistically significant. He held slightly larger leads of up to 4-points earlier in the week. -- Lydia Saad
