President Roosvelt's proposal, as it is written here, refers to the congress giving a fixed and equivalent amount of money to each of the large parties that are postulated calculated large enough to cover the main needs of the campaign. In addition, the parties can receive a fixed amount of other individuals, as long as they give a detailed report of it. With this second contribution, not necessarily both parties have the same amount, but their campaign budget is reduced proportionally to their voters and does not lend itself to the appearance of incredibly large funds from a single donor that unbalance the campaign or give rise to to suspicions of corruption.
