The presidential campaign seemed consumed last week by Trumpian madness.

The Republican candidates obscured by his fiery presence responded with mighty efforts to gain attention.
Kentucky Sen. Rand Paul demonstrated his view of the tax code in a video in which he ripped into a copy of it with a chain saw, fed it into a wood chipper and set it afire.
