Final answer:
The tactic called cracking, option D) Fracturing, involves diluting the voting power of like-minded voters by spreading them across multiple districts. It's a form of gerrymandering where the party in control redraws district boundaries to minimize the opposition's impact.
Step-by-step explanation:
The tactic that involves spreading like-minded voters across multiple districts to dilute their vote is known as cracking, which is option D) Fracturing. Cracking is a type of gerrymandering where the controlling party draws voting district boundaries in a way that disperses a group of voters with similar political leanings across several districts, minimizing their ability to collectively influence the outcome of elections. This is done by ensuring that their voting power is diluted and doesn't result in a concentrated voting block in any particular district. Gerrymandering can also include 'packing', which is the opposite process of placing a large number of like-minded voters into a single or few districts, therefore reducing their influence in other districts. Both strategies are used to manipulate electoral outcomes in favor of a particular party or group.
