Gerrymandering
of the state governments
when district lines are drawn in a crazy manner to favor one party
No matter where the lines are drawn, some groups and interest are benfited while others are harmed. Nonetheless, many states continued to draw congressional district lines that favored rural over urban areas. In Wesberry vs. Sanders (1964) the Supreme Court adopted the rule od "one person, one vote." Congressional district lines now must be drawn on the basis of population after each 10 year census. According to the Court, the population in each district must be mathmatically equal to other districts in the state. Gerrymandering remains a fact of American political life.
Once every 10 years
I assume it has to be done before the state's presidential primary, because Texas had to postpone its primary, which had been scheduled for the beginning of April, until the end of May due to the congressional redistricting being contested.
Infinite lines can be drawn from a point
Gerrymandering is the term used to describe the process of redrawing district lines to benefit a specific political party or group. This practice aims to manipulate electoral outcomes by concentrating or diluting the voting power of certain demographics within specific districts.
Usually state lines are drawn as a dot dash dot line.
A square by definition has lines of symmetry. Therefore a square cannot be drawn without any lines of symmetry.
The state legislature has the power to draw and redraw congressional district boundaries through a process called redistricting. By manipulating district lines, the legislature can create districts that are either favorable or unfavorable for specific political parties or incumbents. This practice, known as gerrymandering, can significantly influence elections by determining the composition of each district and ultimately impacting the outcome of the race.
