Lower turnout generally means fewer Democrats are voting. “This is the kind of thing that would benefit Steve Garvey,” Mitchell said.

Primary turnout is typically all over the map. But there’s at least the potential for this year to be among the lowest in history due to an all-but-decided presidential primary and voter apathy.

A recent poll from the Public Policy Institute of California found low numbers of likely voters are excited about the election. Less than 40 percent said they were “extremely” or “very” enthusiastic about voting for president this year. That number dropped even further (28 percent) when it came to voting for Congress.
