Explanation:
The largest contributors to political campaigns are typically corporations and wealthy individuals, and the funds generally go to support incumbents. According to data from the Federal Election Commission, corporations and wealthy individuals contribute at least two-thirds of federal-election money. This money can be funneled through various avenues such as advertising that supports or opposes a candidate, 527 groups (tax-exempt political committees), and Super PACs which can accept and spend money without limits. It is important to note that by law, foreign entities cannot make direct contributions to candidates or political parties in the US.
