Doesn't the First Amendment already do that?
A proposal in the Indiana Statehouse would stop homeowners' associations from banning political signs in members' yards and windows near elections.
Of course, people are so busy using the amendment to protect nude dancers and chocolate-smeared artists that it can't possibly be used to protect mere political speech. And as opponents of this measure point out, they're just trying to make areas look nice, and we all know how important that is. Besides, people "who join homeowners associations know the rules before they buy their property." Give up the property or your constitutional rights. Nice choice.
