A closely watched Assembly race in Northern California looked too close to call on Election Night, with Republican Jack Sieglock leading Democrat Alyson Huber by less than 2,000 votes in AD 10.

Huber had 46 percent to 47.2 percent for Sieglock, with 98.3 percent of the precincts counted Wednesday morning.

Sieglock campaign spokesman Tim Clark said he expected the race to take several days to decide, with both candidates waiting to see how provisional and absentee ballots came out.

"All in all, I'd rather be where we are than she is right now," Clark said.

He added that Republican vote totals may have been suppressed by a mysterious robocall Tuesday evening that told GOP voters to stay home because the presidential race had already been decided.

Clark said he'd received reports of the calls in both AD 10 and the overlapping 3rd Congressional District, as well as in other contested races up and down the state.

"We'll find out in the coming days where it came from," he said. "There's a lot of investigation to do."

A call for Huber's campaign was not returned early Wednesday.
