The two sides have blocked off airtime in a dozen states, including both traditional battlegrounds and states that were once considered safely Democratic or safely Republican.
Trumps campaign, flush with cash, has leapt to an early lead in television spending. The Trump campaign has reserved more than $150 million in advertising time in 12 states, including $40 million in Florida alone, the presidents adopted home state.
President Trumps unprecedented fundraising has equipped his campaign with the resources to do what we always planned defend the states he won in 2016 and add some where he was close last time, said Tim Murtaugh, Trumps campaign spokesman. We know that a lot of Americans know Joe Bidens name, but they dont know much about him. Were changing that and Americans will know that hes an empty vessel being filled with the radical agenda of the extreme left.
Trumps campaign has already reserved $16 million in Pennsylvania, $13 million in Michigan and $7.8 million in Wisconsin, the three Rust Belt states that propelled him over the electoral college finish line in 2016. 
There are signs that Trump hopes to expand on his victory four years ago: The campaign has blocked off $7 million in airtime in New Hampshire, where Hillary ClintonHillary Diane Rodham ClintonNSA leaker Reality Winner tests positive for coronavirus at Texas federal prisonTrump campaign leans into Goya controversy in new Spanish adsBiden leads Trump by 8 points, holds big advantage among undecided voters: pollMORE won by just 2,700 votes, and the overlapping Boston media market. And the Trump team has reserved $14 million in airtime in Minnesota, a state he lost by just 45,000 votes and one that has not voted for a Republican presidential candidate since 1972. The Trump campaign has reserved $6.2 million in airtime in Nevada, public records show.
But Trump will also spend millions defending states he won easily in 2016.
The campaign has reserved $18 million in airtime in Ohio, where Trump beat Clinton by 8 percentage points; and $5.8 million in Iowa, where he won by almost 10 points.
The Trump team will also spend at least $16.9 million in North Carolina and $7 million in Arizona, two states he won by just 3 points in 2016.
It does seem like there will be a healthy number of contested states this time around, and there seems to be plenty of money out there to run these ads as well, said Travis Ridout, a political scientist at Washington State University and a co-director of the Wesleyan Media Project, which tracks political ad spending.
Bidens campaign has been slower to reserve airtime, though it said Tuesday it would spend $15 million on television advertisements in the next week. Biden will buy airtime in Arizona, Florida, Michigan, North Carolina, Pennsylvania and Wisconsin, and he will air advertisements during the opening games of Major League Baseballs abbreviated season later this week.
Before those advertisements are placed, Bidens team had reserved only $2.4 million in airtime, spread between those six states between now and Election Day.
We have outraised the Trump campaign for two straight months, are closing the cash gap, and will run a robust paid media program between now and Election Day that makes the positive case for Joe Bidens trusted and tested leadership during a time of profound crisis, said Matt Hill, a Biden campaign spokesman. We will be up on the air and online making sure that voters know there is only one candidate who is going to get the virus under control, save the economy, and restore the soul of America: Joe Biden.
The bulk of the spending on the Democratic side comes from Priorities USA, a super PAC that has already reserved almost $50 million in airtime from now until Election Day. The group has reserved tens of millions in airtime in 17 media markets across the same six states where Biden is focused, according to advertising data analyzed by The Hill.
Priorities USA has already purchased more than $5 million in airtime in Detroit and in Tampa and Orlando, Fla. They will spend nearly $5 million in Phoenix.
Our spending is geared towards getting to 270 [electoral votes], so that doesnt mean that we dont think other states are in play beyond where were spending, said Josh Schwerin, the groups senior adviser. If we focus on fewer states, we can make a bigger impact in those states. I should say that plans can always change.
On the Republican side, America First Action, Trumps main super PAC, has reserved $29 million in airtime. The lions share of that spending will take place in the Tampa and Orlando markets, which together account for $16.1 million in reservations. America First Action has also blocked off nearly $9 million between the Charlotte and Raleigh markets in North Carolina.
Altogether, Democratic outside groups have blocked off $80 million in airtime dedicated to the presidential contest so far, while Republican spending is almost entirely coming from America First Action. 
The initial spending is certain to explode, both as the campaigns and outside groups collect more money and as the battleground shifts. Polls suggest states like Georgia and Texas may be in play, though no Democratic groups have purchased airtime there. And Democrats may feel pressure to defend states like Minnesota and Nevada, if Trumps ads move the needle.
Though campaigns are spending more than ever on digital advertising on platforms like Facebook and Google, television especially local broadcast news and sports is still king.
Advertising spending in some ways responds to how much the campaigns are able to raise, and Donald Trump is a very effective fundraiser for himself and also for Democrats. Theyre bringing in the cash, Ridout said. 
In the midst of a pandemic, he added, television is likely to play an even more outsize role: Its hard to spend that money on political rallies and door-knocking this time around, so whats left?
