Around here they are pushing the 15% ethanol blends as a green alternative, better for the environment and so on. Hasn't been mandated just yet though. I avoid any ethanol in all my small engines. As stated before it is OK in a vehicle that gets used all the time (your car or truck) but for engines that sit for extended periods it isn't a good choice. If it is all you can get, add a fuel treatment like SeaFoam to every tank of gas. That helps counteract the bad effects of the ethanol.
