The NDP is less than impressed with Liberal Leader Michael Ignatieff's ability to wring concessions from the government in return for his party's support. You will no doubt hear the following from every NDP spinner on every platform over the next 24-48 hours:

In 2005, Jack Layton won $4.6 billion in new investments in housing and transit in exchange for supporting the minority government of Paul Martin.

In 2009, Michael Ignatieff got a working group and an opposition day for supporting the minority government of Stephen Harper.
