On unrealistic hopes

If there's any good news in the Libs' strategy for the upcoming session of Parliament, it's that Michael Ignatieff finally seems to have figured out that there's a better chance of getting results in a Parliamentary committee where his party can cooperate with the NDP and Bloc than in a two-party meeting where Pierre Poilievre holds a veto. But shouldn't he also have noticed over the past year-plus that counting on "good faith" from the Cons (rather than getting any positive steps in writing) is a sucker's bet?
