Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
Presidential election campaign fund checkoff
The Presidential nominee of each major party (one whose candidate received more than 25% of the vote in the previous election) may become eligible for a public grant of $81.78 million (if the election were held in 2007). To be eligible to receive the public funds, the candidate must limit spending to the amount of the grant and cannot accept private contributions for the campaign. After the conventions, candidates raise funds for general election legal and accounting compliance funds (GELACs), which are to exclusively to pay for legal and accounting expenses for the campaign. They can also pay for recounts, since that is considered a "winding down" expense allowed under regulations. These expenditures are not subject the above limit. However, in 2007, the FEC ruled that up to 5% of broadcast advertising can be paid for using GELACs, since that is time nominally spent on the required disclaimers under the Bipartisan Campaign Reform Act, namely I approve this message.
