Statewide, general election turnout leaves much to be desired.
In 2022, only 51.5 percent of eligible Californians voted in the November election.
Bushey says the primaries have even more room for improvement.
"Look at four years ago in our last presidential primary election, where only 52 percent of our registered voters turned out and cast their ballot, so those 52 percent of people made the decision for 100 percent of the voters," Bushey said. "It's important to get out, there are local races, there are state races and federal races."

Though the deadline to register to vote in the March 5 primary is Tuesday at midnight, in California there are still options if you miss it.
"We can do what they call conditional voter registration starting (Wednesday) through Election Day," Bushey said. "Any voter can come down to any of our 100 Plus vote centers, or they can come down to our office, and they fill out a conditional voter registration."
From there, people are given a ballot and can return it with a conditional voter registration envelope.
"We will take it back to our office, enter their information and then be able to count their ballot," Bushey said. "So it's not too late."

If you head to the state website, not only can you register to vote but you can also check on your registration statue, confirm your address and other details.
Bushey reminds everyone that the process is not difficult.
"You need to get out and cast the vote to have your voice heard," she said. "You're only getting one vote and that's how you make your voice heard.
