When Obama flip-flops in a direction that I prefer, should I still roll out the “all statements from Barack Obama come with an expiration date, all of them” disclaimer?

From the Houston Chronicle:

President-elect Barack Obama has shelved a proposal to slap the oil and gas companies with a new windfall profits tax because oil prices have dropped so much in recent months, the transition team confirmed today.
“President-elect Obama announced the policy during the campaign because oil prices were above $80 per barrel,” a transition aide said. “They are currently below that now and expected to stay below that.”
Obama’s proposal had called for using the proceeds from the tax to give American consumers an energy rebate worth up to $500 per individual or $1,000 per married couple.

I’ll believe in a windfall profits tax when it’s proposed for lawyers who win huge damages, for Hollywood blockbusters, etc., not just the politically unpopular industry du jour…
