The campaign and the committee said that they had a combined $100 million in cash on hand, and that they had raised more money online in the second quarter than in the first half of 2018. Mr. Trump and his committees raised $54 million, they said, and the Republican National Committee raised $51 million, money that can be plowed into television and digital advertising, get-out-the-vote efforts and other activities related to the 2020 election.
While Mr. Trump may be trailing the Democratic front-runners in the polls, his second-quarter numbers were a reminder that as an incumbent, he has advantages that were unavailable to him as an untraditional, first-time candidate in 2016.
