Won't that logic actually work against Abdul Abdi seeing that NDP has 20% in his district while the liberals have 43%??
He may get 40% of the vote but still lose because NDP voters chose to go liberal at the last moment.

In Abdul Abdi's case, his riding was a Conservative stronghold for about a decade and his has the backing of former Conservative MP John Baird ( who won 45% of the vote in 2011). He could win. It doesn't seem likely, but it could happen.
