Today’s pair of Zogby polls hold good news for Barack Obama, showing him well ahead in North Carolina, with 51 percent support compared to Hillary Rodham Clinton’s 37 percent. Twelve percent were undecided or choosing someone else. The telephone survey was done May 3-4. Obama gained 3 points while Clinton lost 3 from the previous survey, just one day earlier.

In Indiana, Zogby says, “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.”

As usual, in North Carolina Obama has strong support among African Americans (79 percent) while Clinton holds the majority among whites (52 percent).

The margin of error for both polls was +/- 3.9 percent.

And, for what it’s worth, Suffolk University says the “Indiana bellwether area of Delaware County points to Hillary Clinton to win.” Clinton leads there 44 percent to 37 percent, according to its Monday night survey.
