Lower fuel prices will spur the economy as people have more money to spend, they will travel more, buy more......or use it to pay for Obamacare which is a drain on the economy.
Or another way of looking at it, Obama's economy can only work in perfect weather and high energy prices.
However, the last few winters have been brutally bad in the Upper Midwest and Northeast. When eastern Massachusetts got essentially two years of normal snowfall in the space of a month and the Buffalo area experienced this past winter one of the most brutal bouts of lake effect snow, no wonder the US economy slowed down over the winter. I'd ask serious questions if the April-June quarter is bad, though.
