Thank you very much.
I'll also stay with our professor for a moment.
You enlightened me on a couple of things. One is that it sounds like politicians are traffic lights to voters on these things. I hesitate to explore what signal Donald Trump is sending to you and other folks right now, because it confuses me. But you also suggested something regarding a fear of change.
Can you remind me again about the California example and whether this is empirical or anecdotal, the notion that people are reluctant to sign up to campaigns unless they express a 70% or greater favourability of change a year out? I think that's what you told us.
