Final answer:
An individual can give up to $36,500 to a national political party committee, $2,900 per candidate per election, and $5,000 to a PAC, with these amounts being subject to biennial inflation adjustments.
Step-by-step explanation:
The limit on how much an individual can give to a political party in the United States is currently $36,500 to a national party committee. Additionally, individuals can donate $2,900 per candidate per election, and up to $5,000 to a Political Action Committee (PAC). National party committees and their Senatorial campaign committees may contribute up to a combined $51,200 per campaign to each Senate candidate. These limits are adjusted every two years to account for inflation, reflecting the government's aim to ensure a more equal playing field by restricting the influence of wealth in the political process.
