#DumbDonald and the "Rust Belt"

Donald Trump wrote this tweet:

The "Rust Belt" was a nickname given to the area that encompasses Pittsburgh and the Ohio Valley.  Pittsburgh and other cities produced steel that helped build this country with bridges, boats, trains and buildings.

Trump may want to read some history about Pittsburgh and especially the role Pittsburgh played in WWII and about the plant in Ambridge, PA that built the LST Boats which played an important part in WWII.  Public Invited to Welcome USS LST-325 Ship Memorial in Ambridge .
