Measuring Donald Trump’s Mammoth Advantage

The New York Times reports:

Of all the ways Donald Trump has shocked the political system, one of the most significant is how he wins primary after primary with one of the smallest campaign budgets.

He still doesn’t have a super PAC. He skimped on ground organization and field offices. Most important, he spent less on television advertising — typically the single biggest expenditure for a campaign — than any other major candidate, according to an analysis by SMG Delta, a firm that tracks television advertising.

The Donald rewrites the rules.
