Phones were ringing off the hook during the 2006 election season, with Republicans and Democrats blaming one another for bombarding voters with misleading phone messages and robo-calls. Republicans in upstate New York charged Democrats with prank calling voters at the last minute to inform them their voting sites had changed. In return, Democratic congressional candidate Dan Maffei accused the Republican Party of leaving elusive messages that caused voters to mistakenly believe the calls were from him. The robo-calling blitz that year even sparked an FBI investigation when Virginia voters reported calls telling them to stay home on Election Day or face jail time.
