The Federal Election Commission published new rules today for political donations. This is my interpretation (thanks to DSCC staff for help, but any errors are my responsibility). For anyone who has a 5 or 6 figure donation budget has to follow these rules:
A person can give $108,200 total in contributions to all political candidates over a two year election cycle. That is made up of a maximum of $42,700 in contributions to individual candidates. The candidate contributions can be up to $2,300 per election (meaning $2,300 for the primary, and another $2,300 for the general election). That means that someone could "max out" to a total of nine candidates over the two year election cycle.
The other $65,500 ($108,200 - $42,700) is for committees. A person can give up to $28,500 to the DSCC, the DCCC, the DNC, etc. PER YEAR. That means you can max out to one committe twice, or two committees once, etc. The maximum donation to a state party is $10,000 per year (for federal elections, most state parties keep separate accounts for money they can spend on federal elections (congress, senate, presidential) which is subject to this limit, and money they spend on state and local races, which is not). The maximum donation to a PAC is $5,000. All of the committee limitations are per year, the candidate limitations are per election.
All of these are per person, so they would be effectively doubled for a couple acting together.
There are a few other things you can do. If you are hosting a fund raiser, you can spend $1,000 ($2,000 for a couple) that does not count against your maximum. The limit is twice that if it is for a committee. Your own time (as an unpaid volunteer) can be contributed without any limit. You can spend $1,000 ($2,000 for a party committe) on travel expenses as a volunteer without it counting as a contribution.
Caveat, I am not a lawyer. Anyone contemplating approaching these limits should get advise from someone who is a lawyer.
