The maps below show the number of general-election campaign events in each state by the 2020 major-party nominees for President and Vice President.
As can be seen, all 54 campaign events during the first 4 weeks of the 2020 campaign have been concentrated in 10 closely divided battleground states. Pennsylvania has received the most events (10 of the total) and Wisconsin received the second largest number (9 of the total).
These 10 states are among the closely divided states that are rated as either toss-up's or merely leaning toward one party, according to the Cook Political scorecard. Iowa, Texas, Maine's 2nd congressional district, and Nebraska's 2nd congressional district are also rated as either toss-up or leaning, but have yet to receive any attention.
At the moment, 40 states and the District of Columbia have received no general-election attention from the 2020 presidential and vice-presidential candidates.

The reason why voters in only a small handful of states matter in presidential races is that almost all states award all of their electoral votes to the candidate who gets the most votes inside the state. Because of these state winner-take-all laws, candidates have no reason to pay attention to voters unless they live in a state where the race is within a few percentage points.
The situation was similar in 2016 when 94% of the general-election campaign events (375 of the 399) were in just 12 states. The concentration of the 2020 in just a few battleground states is nothing new, and was predicted as early as summer 2019.
