SAN DIEGO (CBS 8) - Two weeks after Election Day, two big local races are still too close to call.
Republican Darrell Issa holds a nearly 4,400 vote advantage over Democratic challenger Doug Applegate in the District 49-race. In Encinitas, Mayor Kristin Gaspar leads County Supervisor Dave Roberts by 368 votes in the race for the District 3-seat.
In San Diego County, there are still 164,000 mail-in and provisional ballots that need to be counted.
Registrar of Voters Michael Vu said it has "been long days and long nights the last two weeks" with all eyes on him.
CBS News 8 political analyst Laura Fink said she believes the numbers will change in the Gaspar/ Roberts race.
"One of the things I feel interesting is that the remaining outstanding ballots - not only are they provisional, but they anticipate a large chunk of them are from UC San Diego students. That will favor Dave Roberts as the Democrat in the race," she said.
In regards to the Congressional race between Issa and Applegate, Fink said the gap is now significant, but anything is possible. "it does look like Congressman Issa will serve another term," she said.
According to election officials, the reason why the votes take so long to count is because mail-in-ballots are often folded in a way that slows down the machines. Provisional ballots also take a long time to be counted because they must be reviewed to make sure they were actually filled out by a registered voter.
Political analysts said the reason for the delay is actually a good thing because it allows more people to participate.
The Lemon Grove mayor's race is also still too close to call, but Raquel Vasquez leads George Gastil by just 33 votes.
