Conservative Senator David Wells says he’s no longer supporting Andrew Scheer’s Conservative party leadership bid — not because of any disagreement over policy but because he didn’t like the “tone” of Scheer’s campaign. And he doesn’t think Scheer can beat Prime Minister Justin Trudeau.

On Thursday, Scheer tweeted, “David and I disagreed on the tone and direction of my campaign, including a policy which will be revealed tomorrow,” Scheer tweeted.

But Wells, who is now supporting Kevin O’Leary, told iPolitics he has “no idea” what Scheer’s talking about.

“I don’t know what he’s announcing tomorrow, or the dispute to which he’s referring,” said Wells.

He said that when he gave Scheer a courtesy call prior to publicly endorsing O’Leary, they only spoke about the tone of the campaign.

“One thing I don’t like, from any of the candidates, is the attacks and the targeting of other candidates. I don’t think its good for the party or tone of the race. Andrew hasn’t been particularly egregious but its been there,” he said.

O’Leary, on the other hand, hasn’t directly attacked other candidates, said Wells. O’Leary has been targeted personally by candidate Lisa Raitt through a website she launched in January.

“When I look at the candidates, all candidates are candidates of merit but when I look at the line up, I think Kevin is the one who can beat Prime Minister Justin Trudeau,” he said.

“I think the prime minister is damaging our country and I think that needs to stop and I think Kevin is the only one equipped to beat him.

“When I spoke with Scheer it wasn’t about policy. It was about tone and approach.”
