Doomed

Shorter EI posturing between the Libs and Cons:

Libs: A 360-hour national threshold is supported by a majority in Parliament and might be worth studying. But we're more than willing to move from it!
Cons: How dare you so much as mention a proposal which we don't like? This proves that you're stuck on an unreasonable position!
Libs: (stunned silence)
Cons: Now start offering us exactly what we want, or this negotiation is over!

In fairness, though, let's acknowledge that the Libs have at least accomplished something by staking any changes on the Cons' willingness to make them look good. After all, they've managed to push the parties who generally agree with their position away from the table to ensure a worse outcome.
