RALEIGH, N.C. — Adding a twist to blue laws in an increasingly red state, North Carolina's Republican-led legislature is toasting a measure intended to keep the booze flowing at the Democratic National Convention.

President Barack Obama and other Democratic Party headliners are set to be in Charlotte for the nominating soirée held every four years, which kicks off with a Labor Day party at a stock car track. The state's government-run liquor stores are closed Sundays and for the Monday holiday, presenting a potential problem for bars, restaurants and hotels needing to replenish depleted alcohol stocks.

The convention is expected to draw tens of thousands of people who will spend millions on food and libations.
