WASHINGTON, May 6 (Reuters) - Barack Obama and Hillary Clinton appeared headed to a split in crucial presidential contests in Indiana and North Carolina on Tuesday, pushing Obama closer to securing the Democratic nomination but keeping Clinton's hopes alive.

CBS News projected a Clinton win in Indiana, which would preserve her slender chances in a prolonged Democratic duel that now moves to the next contest in one week in West Virginia.

Three hours after the CBS projection, other networks had not made a call with 86 percent of the vote counted and Clinton leading 52 percent to 48 percent.

The uncounted votes were in a northwest Indiana county with a sizable black population near Obama's hometown of Chicago, where he could be expected to do well.

Obama swamped Clinton in North Carolina, rebounding from a rough campaign patch fueled by his comments on "bitter" small-town residents and a controversy over racially charged comments by his former pastor, the Rev. Jeremiah Wright.

The two Democrats are embroiled in a grueling battle for the right to represent the party in November's presidential election against Republican John McCain.

"We have seen that it's possible to overcome the politics of division and distraction, that it's possible to overcome the same old negative attacks," Obama told cheering supporters in Raleigh, North Carolina.

Obama, a 46-year-old Illinois senator who would be the first black U.S. president, started his remarks by congratulating Clinton on "what appears to be a victory in the great state of Indiana."

An upbeat Clinton told supporters in Indianapolis: "It's full speed on to the White House."

Clinton, a 60-year-old New York senator and former first lady who would be the country's first woman president, also asked for donations to keep alive her campaign, which has been heavily outspent by Obama.
