Ballot issues arise after Rangel's apparent primary win

(CNN) - While Rep. Charles Rangel of New York celebrates a major primary victory this week - his toughest challenge in 42 years - the state is stepping in on ballot complaints that could wind up changing the results.

New unofficial numbers released Saturday night by the New York City Board of Elections show Rangel ahead of his main challenger, state Sen. Adriano Espaillat, by only two percentage points - 44% to 42% - with just 802 votes separating them and more than 3,000 votes unaccounted for.
