Presidential Primary Debates Can Make — And Break — A Campaign

It might sound strange, but presidential primary debates are arguably more important than general election debates. Primary voters have weak initial preferences and can vacillate among candidates, so they can be heavily influenced by events like debates. Primary debates do not attract nearly as many eyeballs as general election debates, but they still garner millions of viewers and can persuade more voters than a general election face-off, when most voters have already chosen their partisan camps.
