You'd have to make sure there were no state or local laws against it in your home area, and you'd have to make sure that you followed FEC regulations - - then there are ebay's own rules:
http://pages.ebay.com/help/policies/items-ov.htmlFor example:
http://pages.ebay.com/help/policies/fundraising.htmlCharity or Fundraising Listings
Charitable fundraising is a highly regulated area subject to numerous state and federal laws. eBay allows sellers to list items and collect proceeds (in whole or in part) on behalf of charity either with eBay Giving Works (the dedicated program for charity listings on eBay) or without eBay Giving Works (as long as the listings meet our specific guidelines for charitable solicitations).
Violations of this policy may result in a range of actions, including:
Listing cancellation
Limits on account privileges
Account suspension
Forfeit of eBay fees on cancelled listings
Loss of PowerSeller status
http://pages.ebay.com/help/policies/politicalmem.htmlReproduction Political Memorabilia
Sellers listing items in the political categories must protect potential buyers by abiding by the Hobby Protection Act.
http://apic.us/Lib/HPA.aspSellers must also be aware of this law to protect themselves from any violations of Federal law which could impose fines, penalties, or both.
Political Memorabilia reproductions and fantasy items must be clearly marked as such. Sellers must also state this in the item description.
The font size of this reference text must be identical to that of the rest of the listing.
These items must be listed in the Repros, Fantasy Items category, which resides under the Political Memorabilia > U.S. category
This policy applies to all political memorabilia, including buttons, posters, literature, stickers, or other forms of political advertisements and candidate promotions.
Violations of this policy may result in a range of actions, including:
Listing cancellation
Limits on account privileges
Account suspension
Forfeit of eBay fees on cancelled listings
Loss of PowerSeller status
