Gerrymandering existed before either political party did. It has been used and abused by both of them. Gov. Patrick Henry of Virginia gerrymandered a district in an attempt to prevent James Madison from being elected to Congress. Had Henry been successful we would not have had our Bill of Rights. (Madison is the author of them, with a lot of help and advice.) While the Supreme Court decided that it is not a Constitutional issue it's doing so is not a nail in the coffin of free and fair elections. Gerrymandering does make them more difficult to achieve but throughout American history on the whole we have had free and fair elections. The practice of gerrymandering is much better than what was done in the 1850's in (Bloody) Kansas.
