Maybe you could walk me through your math? California has 55 electoral votes, so how could there be a 129 vote difference in the electoral college if you remove California?
The electoral vote was 306 to 232 = 74 vote margin. If you drop out California’s 55 electoral votes, that would reduce the Democrat side by 55 votes (306 to 177). 74 + 55 = 129. 306 - 177 = 129.
The current 306 to 232 margin came from the Wikipedia article on the 2016 Presidential Election.
