Chart illustrating how the U.S. presidential election works, highlighting the distinction between the popular vote and the Electoral College system.

Let’s solve this step by step.

We are told:
- There are 538 total electoral votes.
- A candidate needs at least 270 to win (half of 538 is 269, so 270 is the majority).
- The number of electors each state has = number of representatives + number of senators.
- Every state has exactly 2 senators.
- California has 55 electors.

So, if California has 55 electors, and 2 of those come from its 2 senators, then the rest must come from its representatives.

That means:
Electoral votes = Representatives + Senators
→ 55 = Representatives + 2

Now subtract 2 from both sides:
Representatives = 55 - 2 = 53

So California has 53 representatives.

Final Answer:
53
