Nope.  The mortgage interest deduction was an itemized deduction.  Only people with very large mortgages ever got any benefit from it, because even on $300k+ loans, your annual interest payments were not higher than the standard deduction anyway.

This is complete bullshit. State income tax,  sales tax,  property tax,  mortgage interest,  AND charitable contributions all went in there, plus,  the standard deduction was much lower. A third of all taxpayers used to itemize.
