{{main|Political campaign}}
When elections are called, politicians and their supporters attempt to influence policy by competing directly for the votes of constituents in what are called campaigns.  Supporters for a campaign can be either formally organized or loosely affiliated, and frequently utilize [[campaign advertising]]. It is common for political scientists to attempt to predict elections via [[political forecasting]] methods.

The most expensive election campaign included US$7 billion spent on the [[2012 United States presidential election]] and is followed by the US$5 billion spent on the [[2014 Indian general election]].<ref>{{Cite web |url = http://www.ndtv.com/elections/article/election-2014/india-s-spend-on-elections-could-challenge-us-record-report-493685 |title = India's spend on elections could challenge US record: report |website = NDTV.com |access-date = 25 February 2016}}</ref>
