Task: Question Answering
Input (English): Passage: Kerry would later state that "the widespread irregularities make it impossible to know for certain that the [Ohio] outcome reflected the will of the voters." In the same article, Democratic National Committee Chairman Howard Dean said "I'm not confident that the election in Ohio was fairly decided... We know that there was substantial voter suppression, and the machines were not reliable. It should not be a surprise that the Republicans are willing to do things that are unethical to manipulate elections. That's what we suspect has happened." Question: Which Democratic official supported Kerry's theory about the Ohio votes?
Output (English): Howard Dean
