Which Canadian Leader Has Igg on His Face?

One of Canada's leaders has Igg all over his face. Can you guess who it is, boys and girls?

Hint:

He was critical of Israel before he supported Israel.
He was against the budget before he supported the budget.
He denounced deficits before he urged more spending.
He was for propping up the Conservatives before he was against propping up the Conservatives.

He was for an election before he backed down on an election.
He was for the Coalition before he was against the Coalition.

This politician has more turns than a weather vane.

The National Post's McParland calls it the Iggy shuffle.

And that's the way the ain't-got-no-finger-in-the-wind Ball bounces.
