The ballot initiative on independent redistricting held onto its fragile lead in Friday’s updated election tally, with the proposition still passing by about 2,900 votes.

Proposition 4 has alternated between victory and defeat at various points this week, as election officials continue to add up votes from around the state. As of Friday, the initiative — which would call for the creation of an independent redistricting commission — was leading by 50.15 percent to 49.85 percent, with about 978,000 votes counted.

The proposition, billed as an anti-gerrymandering measure, would establish a commission that would redraw the state's voting districts every decade. The state Legislature could follow or ignore the commission's recommended map.

The vote totals will continue to change until counties complete their ballot canvassing Tuesday.
