This has been true for mucher longer than than the last 4-6 years. Republican Congresses and Presidents have added more to the deficit over the last 40 years than Democrat administrations.
A couple of points:
1) My sole response was in terms of Trump supposedly being a "smart businessman," yet he's by far been the worst on the budget deficit
2) I'm not sure the way you're saying this deserves much merit - because some deficits run up by Administration B were enforced on them by Administration A.
Obama ran a huge deficit early - because of the subprime mortgage collapse and the two wars in the Middle East, neither of which he caused. But he likewise made it far worse with Obamacare (over time) as well.
Reagan's deficits were made far worse by the Fed clamping down on inflation while currently increasing unemployment, the air traffic controller strike that necessitated the federal government to keep airlines afloat, and the fact there was a Cold War ongoing.
That doesn't absolve any one of them, it just provides the fact there's context.
And neither Reagan nor Obama claimed to be (or was claimed to be) a successful businessman, which was more of the larger point.
In the end, if AOC presented a budget plan during a campaign that would balance the budget tomorrow, her own allies would demand her head on a platter "because you cut X, which people need!" The same would be true if a conservative did the same thing.
