Tory campaign worker in Guelph tweeted robocall warning two days before election - 2012-03-09

OTTAWA — On the day "Pierre Poutine" activated the burner cellphone used to launch his robocall blitz on voters in Guelph, Ont., a young Conservative campaign worker sent out a message on Twitter warning of "voter suppression calls" aimed at his party.
Andrew Prescott, deputy campaign manager to Guelph Conservative candidate Marty Burke, tweeted on April 30, "Anti-#CPC voter suppression phone calls currently underway in Guelph, suspecting #LPC #elxn41" — referencing the Twitter shorthand for the Liberal Party of Canada and the 41st general election.
Prescott, a self-described cellphone expert, followed up a few minutes later with another tweet claiming that these phone calls were "using spoofed Caller-ID of Burke campaign. I 'wonder' who it could be . . ."
