WASHINGTON, D.C. (AP)-- As Democrats focus on their party's crowded primary, President Donald Trump is blanketing battleground states with online advertising that could help set the narrative for the 2020 campaign.
The blitz of ads running in states including Michigan, Florida, Wisconsin and Pennsylvania is alarming some Democrats.
They worry about the more than $10 million Trump and his allies have already spent on digital advertising.
That's a drop compared to the $1 billion his campaign alone could spend. But for now, it's going largely unanswered.
Trump's early head start combined with his massive fundraising operation has stirred concern that it could be difficult for the eventual Democratic nominee to catch up.
Democratic outside groups say they will soon start spending to counter Trump's message.
