Turner campaigned rallying support against the proposed FTA, an agreement that he said would lead to the abandonment of Canada's political sovereignty to the United States. His performance in the debate and his attacks on Mulroney and the FTA, where he accused the Progressive Conservative Prime Minister of selling Canada out with one signature of a pen, raised his poll numbers, and soon the Liberals were hoping for a majority. This prompted the Progressive Conservatives to stop the relatively calm campaign they had been running, and go with Allan Gregg's suggestion of "bombing the bridge" that joined anti-FTA voters and the Liberals; Turner's backbone. The ads focused on Turner's leadership struggles, and combined with over $6 million in pro-FTA ads, stopped Turner's momentum. Also not helping the Liberals was that the NDP had opposed the FTA as well (though not as vocally); this likely resulted in vote-splitting between the opposition parties. Although most Canadians voted for parties opposed to free trade, the Tories were returned with a majority government, and implemented the deal.
