My answer, big money wants to buy the elections by shouting out the individual voter.  Big money corrupts our election process.

"Why outside groups are pouring record amounts of money into this year’s midterm elections" PBS NewsHour 4/16/2014

Excerpt

JUDY WOODRUFF (NewsHour):  Last night was the deadline for political candidates, parties and some outside groups to report how much money they have raised and spent in the first three months of this election year.  One thing is clear:  Organizations not officially linked to the candidates are spending at record levels.

Combined, these outside groups have poured in more than $57 million so far this cycle.  That outpaces any election in American history at this calendar date, except the 2012 presidential election, which came on the heels of the Supreme Court ruling prohibiting restrictions on spending.

Now, a quarter of all this year’s money has been spent in just six states, where some of the key Senate races are playing out.  Overall, more money has been spent already in this election than the entire 2000 presidential election, and the races have barely just begun.

And here to talk about what all this means is Sheila Krumholz.  She’s the executive director of the Center for Responsive Politics.  It’s a research group that tracks money in U.S. politics.  And David Keating, he’s the president of the Center for Competitive Politics.  It’s a nonprofit organization that promotes deregulation of campaign finance.
