Washington, DC (LifeNews.com) -- With two more Democratic primary battles coming up next week, Barack Obama holds a lead in North Carolina while Hillary Clinton has the advantage in Indiana. Should the candidates split the two states, the contentious primary could continue further into May in three other states.

Obama has held a consistent lead in North Carolina for months, in part because of the large number of African-American voters there.

The newest polls from Rasmussen and Zogby show Obama with leads of 9 and 16 percent, respectively. He leads Clinton 49-40 in the Rasmussen poll and 50-34 in the Zogby poll.

Earlier this week, a Research 2000 survey found Obama ahead 51-44 and a Mason-Dixon survey had him leading 49-42.

Clinton has gained ground since late April from the double digit lead Obama had earlier in April, but it appears Obama will likely win the state handily.

In Indiana, Obama lost the small lead he had a couple of weeks ago and Clinton has pulled out to a sizable enough lead that it appears she will likely carry the state.

A new Zogby poll shows a 42-42 tie between the candidates, but other surveys have Clinton well ahead.

A Downs Center poll released today shows 52-45 lead for Clinton, a Rasmussen poll has her ahead 46-41, a PPP survey has Clinton up 50-42, and a TeleReseach poll has Clinton leading 48-38.

Combined together, the polls show Clinton leading her pro-abortion counterpart by about six percent.

Should the candidates split the two states and continue battling for the nomination, they will head to West Virginia on May 13, where Clinton is expected to fare well. Oregon and Kentucky Democrats would then head to the polls on May 20.

In June, Democrats in Puerto Rico, Montana and South Dakota vote for the presidential candidates.
