Final answer:
A common tactic in a financial-incentive political strategy is political contributions.
Step-by-step explanation:
In a financial-incentive political strategy, a common tactic is political contributions. Interest groups and individuals with financial resources contribute to political campaigns or donate to politicians who support their interests. These contributions can help to influence the decision-making process and gain support for specific policies or legislation.
For example, wealthy individuals or companies may donate to a candidate's campaign and expect favorable treatment in return. They may also fund outside groups to generate support for their agenda and hire expert witnesses to provide testimony supporting their position. This tactic allows them to directly influence policy and shape the political landscape.
