As usual, you miss the point.     How does Flanagan figure that Scheer will win over disaffected Liberals when he couldn't convincingly win over his own party?   He won because he was a resounding SECOND choice candidate.     He'll likely remain the second choice candidate for many Canadians too.    Why?   Because he's had 13 years in politics to make a name for himself and he's largely "Andrew WHO?" to most Canadians.
