How is this still being told?

The expansion was not very strong, the tax cuts pushed it to its potential (to be fair, I think we have reached the line of demarcation)

And increase spending after the recession is over?
Obama actually put a commission together that suggested a reduction in growth of spending (not even cuts, reduction in growth). These were labeled as “draconian” and thoroughly ignored.

The recovery was slow, as economists had predicted it would be, but the unemployment rate in 2017 was 4.1%, a 17-year low. Hard to argue the economy needed a nudge.

Other than the fact that Trumps policy decisions made it even lower.

It briefly went a little lower, but economists generally consider 4% full employment. There was no need for a boost and a good argument that the tax cuts just made the rich richer and added to the debt.

But hey, they may have made the 2020 election a bit closer.

The data disputes all of that 100%

How? Revenue went up, but less than it had. The economy expanded, but at a lower rate than the preceding years. Corporations, instead of doing a bunch of hiring, did a bunch of stock buybacks. So, the rich got richer, the economy was already expanding, so not much of a nudge, and the debt almost certainly would be lower today without the tax cuts.

The vast majority of the gains went to the people in the lower income brackets.

False.
