So sorry. My memory is not faulty. I remdember seeing and hearing HW. Bush saying that the American people could pay the same as Europeans. Maybe you need to go to your local library and look it up.
Gore was an almost, unheard of senator from Tennessee. This was before Clinton.
First, saying "could" is very different from saying "should". Saying that if you walk around the east side of town at 1AM you could get mugged, is not at all like saying that you should get mugged.
Second, Gore had a book called "Earth in the Balance," which was the subject of many campaign debates from mid 1992 on.
GHWBush never advocated European gas prices.
