Trump also breaks 6 million votes in California which is the most votes he got in any state in the country
We talk a lot about the Trump-era EC bias against Democrats, but these people are effectively disenfranchised on the presidential level too. More Trump voters than any other state, and not a one of those Trump votes has any effect whatsoever on the election's outcome.
While won't happen, if they used the British or Canadian system, Democrats would win seats in most red states and GOP in most blue states, otherwise a parliamentary system so would use congressional districts. If they used PR like most of Europe does, 64% of representation in California would be Democrat, 34% GOP. Now like Nebraska and Maine, California could split its electoral votes, but seems dumb idea unless red states reciprocate otherwise just helping GOP. Other option would be have electoral votes go proportionally, not winner take all, but again all not just some need to do this. If allocated proportionally, it would be 36 for Biden, 19 for Trump in California.
