The 2014 election featured challengers and incumbents with record high campaign expenditures. But just how much must a candidate spend to win an election? According to our data, multimillion dollar campaigns don't always guarantee elected office. We analyzed the total campaign expenditures for ten of the most expensive Senate and House races in 2014. The costs of maintaining a staff, running political advertisements, and coordinating get-out-the-vote efforts were successful for some, and ultimately ineffective for others.
Of note are the additions of congressional leaders Mitch McConnell and John Boehner to our list. Despite their tenure in government, both spent millions to ensure reelection. McConnell faced a particularly strong challenge from Kentucky Secretary of State Alison Grimes, also a member of this list.
