Final answer:
When interest groups spend substantial amounts of money solely to defeat a political candidate, issues such as distortion of electoral outcomes and strengthening of democratic values can arise.
Step-by-step explanation:
When interest groups spend substantial amounts of money solely to defeat a political candidate, several issues can arise. One of the main issues is the distortion of electoral outcomes. When interest groups pour large amounts of money into a campaign, it can tip the scales in favor of the candidate they support, potentially undermining the democratic process. Another issue that may arise is the strengthening of democratic values. Some argue that excessive spending by interest groups can highlight the need for campaign finance reform and transparency in the political system. Lastly, while increased voter engagement may occur as a result of interest group spending, it is not directly caused by it.
