Can you split up each puzzle so that more than half of the groups are purple groups?

In a town of 25 people, there are 15 yellow voters and 10 green voters arranged in the map on the right. Before an election, these 25 people are split up into 5 districts with 5 people in each district.
The winner of each district is the color that shows up the most in that district. The winner of the election is the color that wins the most districts. In the example on the right, green won the election even though there are fewer green voters. Drawing districts to enable this is called gerrymandering.
