You can see here what happened when the Democrats or the Republicans could have more/less votes at the 2024 presidential elections. You can change the voter results with the R and D button (R means 0,1% more republican votes and D 0,1% more democratic). You can also change it with the arrow keys (right means more democratic and left more republican :D). The popular vote is given in the upper left. The electoral college votes are given at the bottom.
