BOSTON (AP) -- A group backed by the conservative Koch Brothers plans to spend more than $125 million on the November elections.
The investment marks a significant escalation for the Koch Brothers' main campaign arm. Americans For Prosperity plans to increase television advertising across the country, improve voter data collection and strengthen its 31-state ground operation.
A senior official with direct knowledge of the plans confirms the election blueprint. It's outlined in a memo to Republican donors this spring. The official confirms the memo's authenticity but isn't authorized to discuss it publicly.
The group has already spent more than $20 million this year in advance of the midterms, which will decide the balance of power in Congress for President Barack Obama's final years in office.
