Supreme Court to hear potentially landmark Wisconsin case on partisan gerrymandering

The Supreme Court declared Monday that it will consider whether gerrymandered election maps favoring one political party over another violate the Constitution, a potentially fundamental change in the way American elections are conducted.

The justices regularly are called to invalidate state electoral maps that have been illegally drawn to reduce the influence of racial minorities by depressing the impact of their votes.

But the Supreme Court has long been tolerant of partisan gerrymandering - and some justices have thought that the court shouldn't even be involved. A finding otherwise would have a revolutionary impact on the reapportionment that will take place after the 2020 election and could come at the expense of Republicans, who control the process in the majority of states.
