LAS VEGAS (AP) - Big voter turnout and a switch from precincts to fewer at-large voting centers are being blamed for long election day lines in some of Nevada's most populous areas.

In three counties, polls stayed open for several hours after official closing time on Tuesday to accommodate people in line.

State elections official Wayne Thorley says there weren't reports of fraud or illegal activity.

In Las Vegas, a county spokesman says 82 of 172 sites stayed open late to give everyone in line time to vote.

In Reno, the last site closed three hours late.

Thorley says changes could follow county post-election reports due in January.
