UTICA, New York-On the strength of good polling numbers on the final day before the primary elections in Indiana and North Carolina, Barack Obama of Illinois holds a convincing lead in North Carolina, but the race is simply too close to call in Indiana, the latest Zogby two-day telephone tracking poll shows.

The pair of surveys of the Democratic presidential contests shows Obama with a significant 14-point lead in North Carolina, winning 51% support to Hillary Clinton’s 37%. Another 12% said they were either favoring someone else or were as yet undecided. In Indiana, the race is clear as mud, as Obama holds a statistically insignificant lead of two points, winning 45% support to Clinton’s 43% support, with 12% either undecided or favoring someone else.
