This election season has brought a torrent of campaign spending from outside interest groups, and nowhere is the spending on better display than in Colorado.
Interest groups have been flooding Colorado with a level of advertising that goes well beyond the typical election year bombardment.
Colorado has become such an attractive destination for outside political money this year because of the state's bellwether status, its many competitive races and its relatively cheap media rates.
The top target is the Senate contest between Democratic Sen. Michael Bennet and Republican Ken Buck, a race that could help determine the control of Congress.
Competitive House races in the state have also been affected by the spending.
