The most important thing political junkies might need this week is patience.

With so many key races expected to be tight, officials are warning it could takes days — perhaps even more than a week — to know the outcome of Tuesday’s primary election.

Here are some important things to watch as the results roll in:

1. The fight for the second top spot

Most polls and pundits say Democrat Xavier Becerra is likely to be the top voter-getter in the primary to replace Gavin Newsom as California governor.

Until recently, it was assumed that Republican Fox News host Steve Hilton would also advance, especially after he was endorsed by President Trump.

But a new poll suggested Hilton was in a tight race for second place with Democratic billionaire Tom Steyer, who is spending heavily from his own fortune. If he is successful, California could see a competitive Democrat-versus-Democrat general election come November.

Under California’s election rules, the top two vote-getters move on to the general election regardless of party preference.

Hilton is urging Republicans to unite around him to avoid being shut out. His main GOP opponent is Riverside County Sheriff Chad Bianco.

A few months ago, Hilton and Bianco led some polls amid a crowded Democratic field, prompting fears that Democrats might be locked out of November’s general election. But those concerns have subsided somewhat with Becerra’s rise in the polls.

2. Is the mayor’s race really a tossup?

It’s rare for the Los Angeles mayor’s race to become a national story. But that has happened this year thanks to a showdown few would have predicted.

Former reality TV star Spencer Pratt is a big reason for all the attention, running from the right in a very liberal city. Embattled Mayor Karen Bass is the incumbent, with City Councilwoman Nithya Raman running from the left.

A UC Berkeley-L.A. Times poll released last week found a close race with Bass at 26%, Raman at 25% and Pratt at 22% among likely voters. Other polls have shown Pratt doing better.

Pratt had overshadowed his opponents when it came to social media (and old media) attention. But is that enough to get him into the runoff? Bass has big labor on her side, and we’ll see whether that helps her get out the vote. But Bass is also unpopular, according to polls. Does that give Raman an opening among Democrats who are looking for an alternative?

3. The fallout from California redistricting

When it comes to congressional elections, this should be a good night for Democrats, by design. That’s because California voters last year approved Proposition 50, which redrew congressional districts to favor Democrats.

It was part of a national battle by both red and blue states designed to help their respective parties secure control of Congress. The new California maps give Democrats an advantage in some areas, but it’s still unclear how sweeping the victories will be. There are some notable intra-party battles in “safe” districts as well.

The Times’ data and graphics team has identified a few races to watch:

• Rep. Ken Calvert (R-Corona) lost his seat in redistricting and is now challenging incumbent Young Kim (R-Anaheim Hills) in the 40th District.
• In San Francisco, several factions of the Democratic Party are vying to replace former House Speaker Nancy Pelosi in the 11th District.
• California’s 48th Congressional District in San Diego and Riverside counties has traditionally been red. But the sudden retirement of longtime Republican incumbent Darrell Issa and redistricting puts it in play.
• Veteran Rep. Brad Sherman is facing a strong challenge from fellow Democrat Jake Levine in the 32nd District.
