A simplistic viewpoint. If your revenue us up 3% following the tax cuts and your spending grows by 5% then you can say the tax cut did not contribute to the deficit if you want. But if revenue would have grown at 5% or 8% or 10% without the tax cuts and your spending increased 5% then you could say that the tax cuts contributed to the deficit.
Let's consider then what actually happened. From 2015 to 2017, federal income tax revenue fell. From 2017 to 2019, it rose. So your 'expectation' argument fails. The expectation without the tax cut is that revenue would remain stagnant. Yet with the tax cut, revenue rose. So that proves the tax cut did not contribute to the deficit. Instead, it kept the rise lower than it would have been without the tax cut.
Again, the reason for the rise in the deficit can be directly tied to the rise in spending.
Not sure it's that big of a lie.
At least you acknowledge it as a lie. Moral relativism aside, a lie is a lie. And it is a lie to insinuate that Trump's tax cuts led to higher deficits just as it is a lie to suggest a temporary cut in payroll taxes is directly tied to shortfalls in social security payouts. Lies, lies, lies. Typical DNC BS.
