Gas lines are caused by government rationing, such as we experienced under President Jimmy Carter. Bush has made lots of mistakes, but nothing that stupid.
The free market will give you a take-it-or-leave-it price, but no long lines.
Occasionally you might see a line at a station that is offering a low price as a promotion. Personally, I’d rather pay slightly more and not wait.
The first gas lines I saw were in late 1973/early 1974 when Nixon was President. There was gasoline rationing (odd/even day purchases, etc.), which led to panic buying. People would top off their gas tanks in fear of not being able to find fuel later in the week. I think most of the country’s gasoline supply on any given day was in automobile gas tanks rather than in the distribution system.
In 1979, when the second “oil shock” occurred and Carter was President, I don’t remember gas lines, at least where I lived in the Middle Atlantic. However, the price had gone up substantially and reduced demand.
