Constitution Party Urges Members to Cancel NRA Memberships: Is the NRA a Democratic-Republican Party Front Organization?

Via the Daily Paul, an email from the Missouri Constitution Party:

The Constitution Party suggests that its members consider canceling their memberships with the National Rife Association (NRA). Our candidate, Bill Spaits, MO state rep, http://www.constitutionpartymo.org/index.php?s=Bill+Spaits who has been a long-time NRA member, completed his candidate questionnaire with 100% positive responses. He received this statement as to why the NRA would not endorse him:

"It is the policy of the NRA NOT TO INVOLVE ITSELF IN "THIRD PARTY SITUATIONS."
The NRA will not co-sponsor the Sheriff Mack event.
