Twenty-second Amendment to the United States Constitution
Some argue that the 22nd Amendment and 12th Amendment bar any two-term president from later serving as vice president as well as from succeeding to the presidency from any point in the presidential line of succession. Others contend that the original intent of the 12th Amendment concerns qualification for "service" (age, residence, and citizenship), while the 22nd Amendment, concerns qualifications for "election", and thus (strictly applying the text) a former two-term president is still eligible to "serve" as vice president (neither amendment restricts the number of times an individual can be elected to the vice presidency), and then succeed to the presidency to serve out the balance of the term (though prohibited from running for election to an additional term).
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.
