When attaching a poll to an outbound notification, polls are available for selection based on the order in which they have been sorted. You can sort your polls by dragging them into the preferred order. Hover over the 'move' icon. Click and hold to drag. Using this method, you can keep your most commonly used polls at the top of your list.
