Below is a chart put out by the DNC demonstrating the extent of voting fraud complaints in the United States.

(In case people think the source of the chart is biased, it is based on statistics compiled during an investigation of voting fraud done by the Bush administration).

As for UFO sightings, it seems that in comparison to voter fraud, they are a REAL PROBLEM.
