Year in which North Carolina's Republican-controlled legislature passed a law establishing retention elections for the state Supreme Court, meaning incumbent Justice Bob Edmunds, a Republican who was up for re-election this year, would face only a yes-no retention vote rather than a challenger in a contested race: 2015

Date on which the retention-election law — which one Democratic lawmaker dubbed "the Justice Bob Edmunds Protection Act"— was struck down in Superior Court: 3/4/2016

Date on which the N.C. Supreme Court, with Edmunds recusing himself, upheld the lower court's ruling by a 3-3 vote: 5/6/2016

Margin by which Mike Morgan, a Superior Court judge, defeated Edmunds on Nov. 8, tipping the seven-member court's partisan balance to the Democrats: 54-46

Days after the election that a special North Carolina judicial commission issued a resolution implicitly criticizing a rumored scheme to use next week's special legislative session to add two seats to the Supreme Court that lame-duck Republican Gov. Pat McCrory would fill, reinstating GOP control: 7

Year in which the North Carolina legislature first considered a proposal, which was eventually dropped, to add two Supreme Court seats to be filled by McCrory, allowing him to stack the court without an election: 2013

Date on which John Hood, president of the family foundation of Republican mega-donor and former McCrory budget director Art Pope, had an op-ed published making the case that voters elected Morgan by mistake: 11/21/2016

Number of years ago a trend began nationally, with which this rumored North Carolina move fits, of manipulating for partisan gain the number of justices on state supreme courts — a spike that coincided with state electoral gains by Republicans: 8 to 10

In that time, number of efforts nationwide to alter the number of state supreme court justices, with almost all of those involving court packing for partisan gain: more than 12

Number of states that have already expanded their supreme courts this year for partisan purposes: 2*

Number of seats Georgia's Republican-controlled legislature added this year to its formerly seven-member court, a move opponents said would shape the court politically for years to come: 2

Minimum number of times since 2007 that South Carolina lawmakers have floated proposals, unsuccessful so far, to expand its Supreme Court by two seats: 5

Year in which a Florida lawmaker introduced a bill he later withdrew to expand the state Supreme Court from seven to 15 members, explicitly stating it aimed to overturn a ruling that the state's use of public money for Catholic school vouchers was unconstitutional: 2007
