J.K. -- you are correct. It's on the policy side that the Liberals can be beaten -- sitting on the sidelines taking cheap pot shots at Trudeau won't get the PC's anywhere.  

The PC's need to come out with a strong policy driven program, attack the liberals on their policy shortcomings, and ignore all of the "selfies/hair/other stuff which has absolutely nothing to do with running the country".  The PC's need to come across as serious stewards of the future of the country, leaders, with the ability to rise above petty politics and personal attacks.  

If all the PC party can do is whine, complain, make personal attacks -- and not offer Canadians a solid vision and platform for the future of the country, they'll get demolished in the next election.
