Bertille, can you see a landlord rent a property for less than the mortgage payment?  Rent control would cause that problem in a lot of situations.  Therefore no rentals and no new building for rentals.  Put forth proof where rent control has worked in the past and once it is used it is almost impossible to stop and causes a vicious circle, hurting the people it was supposed to help.  Just like the democratic party does for all the minorities it claims to champion.  Educate yourself before you spout talking points.  Got that boots.
