That was my question. Someone needs to put it to the Federal Election Comission and if it is an illegal solicitation offer, file a complaint.
http://www.fec.gov/pages/brochures/complain.shtml
Filing a Complaint Any person may file a complaint if he or she believes a violation of the Federal Election Campaign Laws or Commission regulations has occurred or is about to occur.
The complaint must be made in writing and sent to the Office of General Counsel, Federal Election Commission, 999 E Street, N.W., Washington, D.C. 20463. The original must be submitted along with three copies, if possible.
Facsimile or e-mail transmissions are not acceptable. A complaint must comply with certain requirements. It must:Provide the full name and address of the person filing the complaint (called the complainant); and Be signed, sworn to and notarized. This means that the notary public's certificate must say "...signed and sworn to before me...," or words that connote the complaint was affirmed by the complainant, (such as under penalty of perjury).
Furthermore, in order for a complaint to be considered complete and proper, it should:
Clearly recite the facts that show specific violations under the Commission's jurisdiction (citations to the law and regulations are not necessary);
Clearly identify each person, committee or group that is alleged to have committed a violation (called the respondent);
Include any documentation supporting the allegations, if available; and
Differentiate between statements based on the complainant's (the person who files the complaint) personal knowledge and those based on information and belief. Statements not based on personal knowledge should identify the source of the information.

Someone with a better background in legalease than I have should go over it. I searched for terms like lottery, solicitation, raffle, etc. I also looked over a number of passages from the table of contents. Didn't see anything that specifically addressed it one way or the other. That is me.
Again, do not file a complain without finding some FEC law that they are violating.
You can also investigate where there are grounds to file a complaint with the Colorado Secretary of the State:
