How will the new tax reform affect the poor and middle class?

The poor and middle class tend not to itemize deductions, so many people will probably have lower taxes or be unaffected. It looks like the really affected will be people who have very unusual situations like huge medical expenses or MFS and forced to itemize or moving expenses.

This seems like a blatantly untrue statement… is there any statistics on the poor not filing for their deductions?
