Who cares... it make the Liberal's and Harper look like crap.
You'd think the Liberals learned from the mistake the PCs made years ago...
The ads do call to mind the fact that he has had a history of being part of a movement has sought even closer ties to US economics and politics...
Now if they'd want to attack Harper they could bring up the fact that he left the Reform party, then came back to run for leadership, then left again... only to join the PCs... then helped bring about the merger....
Heck one could argue that all along it has been a plot by him to become the leader of the far-right
