(CNN) - John McCain said Tuesday he isn't sure if a prolonged Democratic race is benefiting his candidacy, but the exit polls appear to show it is.
The Arizona senator stands to win supporters of both Hillary Clinton and Barack Obama if their candidate does not win.
Only 50 percent of Clinton voters in Pennsylvania said they would support Obama if he is the nominee. Twenty-six percent said they would back McCain over Obama, and 19 percent said they would not vote at all.
Among Obama’s Pennsylvania voters, 67 percent said they would support Clinton if she is the party's nomine. Seventeen percent said they would back McCain instead, and 12 percent said they would stay home.
Clearly, whoever is the Democratic nominee will have some fences to mend.
