The deficit and debt.
I hated it then and I hate it now. I wasn't as politically savvy during Obama's first term as I am now so it didn't bother me as much.
I'm bothered by the trade deficit because it set a new record in 2018 under Trump. One of his primary campaign promises was to reduce the trade deficit and despite his "best" (read: worst) efforts with tariffs, it's only increased under his presidency.
