Virginia redistricting referendum begins

The Virginia redistricting vote is a critical test for both major parties as they battle for momentum ahead of the midterms.

A 'yes' vote would allow the Democratic-controlled General Assembly to implement a new map that could gain the party up to four additional seats.

President Trump has urged supporters to reject the measure, calling it a partisan power grab.

The campaign has seen millions of dollars in spending from national groups, highlighting the state's role as a key political battleground.
