Businessman Rick Caruso's lead over Democrat Rep. Karen Bass has now shrunk to just around 2,000 votes in the Los Angeles mayoral race, as county officials there are sifting through hundreds of thousands of mail-in ballots. 

Caruso, a Republican-turned-Democrat, has so far captured 273,941 votes – about 50.25% – compared to Bass’s 271,246, according to the latest data from the Los Angeles County Registrar-Recorder/County Clerk. 

"As predicted, this is a close race. There are hundreds of thousands of votes to count and as expected we are going to see different results each time," Caruso wrote on Twitter after the results were updated. 

"I continue to be cautiously optimistic about these numbers and look forward to the next series of results in the coming weeks," he added.
