Clinton aides underscore that they have maintained robust organizing efforts in the other core states beyond Pennsylvania and New Hampshire. But they have trained the biggest guns in their arsenal—their advertising dollars and the time of Clinton and top surrogates, such as President Obama and First Lady Michelle Obama—elsewhere.

While Clinton has not visited Wisconsin since April, and appeared just twice in Michigan from June through October, she has virtually taken up residence in Florida, North Carolina, and—after a long absence in September—Ohio. Since June 1, Clinton has appeared 12 times in Ohio, 11 times in Florida, and eight times in North Carolina, according to the campaign tracker maintained by National Journal’s Hotline. Among the core states, only Pennsylvania, with nine appearances, has received anything close to that much attention. Over that same period since June, she’s visited New Hampshire and Colorado three times each, Michigan twice, and Wisconsin not at all. Among states that are more of a reach for Clinton, she’s also visited Nevada four times and Iowa three times. After long consideration, the campaign is making a late push in Arizona, which Democrats have carried only once since 1948; Clinton is visiting the Phoenix area on Wednesday.

Except for Arizona, these states have received enormous advertising spending as well: The Ad Age/Campaign Media Analysis Group tally puts the total at over $26 million in Nevada, about $31 million in Iowa, nearly $34 million in North Carolina, over $52 million in Ohio, and a breathtaking $93.8 million in Florida. Even Georgia has drawn some late Democratic money, if not time from the candidate or her top allies.

Analysts on both sides see strong arguments for Clinton lavishing so much attention on this group of states, even though she does not need any of them to win. Except for Ohio and Iowa, the rest of her “reach states” are all Sunbelt battlegrounds with growing populations of minority voters who reflect the increasingly diverse electorate. Pushing so hard in these Sunbelt states, Greenberg says, “aligns her with the trends of the country and allows for a bigger win.”

One Clinton adviser says her travel schedule has reflected not only the campaign’s priority on each state, but the needs of its organizing efforts; her last visit to Michigan, for instance, came the day before its voter-registration deadline. Her frequent trips to Florida and North Carolina have been tied to her early-voting efforts in both places. “Her travel is not just about press attention. … The trips are also about organizing,” the adviser said.

The reach states also offer Clinton her clearest chance at a knockout blow, because while she does not need to win them, Trump does. In particular, it’s very difficult, if not impossible, to imagine him reaching 270 Electoral College votes if he does not carry both Florida and Ohio, and likely even North Carolina. At the least, she’s forced Trump to also focus on states that he needs more than she does: The Hotline tracker shows that since June 1 he has made a combined 39 appearances in Florida, Ohio, and North Carolina, compared with a combined 15 in Michigan, Wisconsin, and Colorado—all states he’s now targeting. “He’s had to fight the last five months playing defense rather than offense,” says Stewart, a founding partner at the Democratic consulting firm 270 Strategies.
