"'The supporters and opponents wouldn't spend these millions of dollars if these commercials weren't persuading voters,' said Daniel Newman, president of MapLight, a nonpartisan group that analyzes money's role in politics. 'When one side has a specific financial interest, they are going to spend much more because they get such a high return on investment.'"

Reynolds, according to figures from MapLight, a nonpartisan research firm."
