From September 25 to October 1, Donald Trump spent more than eight times as much on television and radio advertising as he did during the prior week, according to newly released tallies from the Associated Press. Trump also widened the map and adopted a more offensive posture, adding five left-leaning states—Colorado, New Hampshire, Nevada, Iowa, and Maine—to the four states where he was already running ads (Florida, Ohio, North Carolina, and Pennsylvania).

During the prior week (September 18 to 24), Trump was outspent by Hillary Clinton by a tally of $19.5 million to $516,000 (according to A.P.’s slightly updated figures for that week). Rounding to the nearest whole number, that’s a ratio of 38-to-1. In the most recent week (September 25 to October 1), Trump cut that ratio to just 4-to-1. Clinton’s ad spending remained essentially constant over the two weeks, dipping slightly from $19.5 million to $19.4 million, while Trump’s rose dramatically, from $516,000 to $4.4 million.
