Political Spectrum

The crosstabs below show the support for Harris and Trump among left, moderate left, center, moderate right, and right voters. These groups are defined by splitting the national electorate in 5 equal sized groups of 20% each. Please note that in the very blue state of California, there are far more left-leaning voters than the national average and far fewer right-leaning voters.

Harris takes almost all (94%) of her core constituency (the left and moderate left). Trump has approximately 15% dissenters among his core constituency (the right and moderate right). Harris also has a significant edge among the centrists (+12%). The large Harris lead is further amplified by having many more left-leaning voters than right-leaning voters in blue California.

Comparisons

In 2020, Biden beat Trump in California by 29.2% while in 2016 Clinton beat Trump by 30.1%. Thus, a Harris lead of 28.0% in her home state, does not seem out of the ordinary. In our previous poll (August 19, 2024), Harris led by 30.6%.
