JohnnyZ,
Obviously you are a Helvey supporter, but your reasons are that "He's a great guy...His staffers are hardcore Republicans". This leaves your only real reason for supporting Helvey the candidate being that "He's a great guy". I am sure that many of the candidates are "great people", but I'm also sure that not many of them have led their companies into bankruptcy -- www.jayhelvey.com.
On another note--Ed Powell's campaign is not a joke. Money, especially the $$$ from New York bankers that Helvey has raised, isn't always indicative of support. If you are supporting Helvey on what he seems to be running on - "Tremenedous International Business Experience" - you are supporting a candidate who is running on false statements. In no way does bankrupting a company translate into a hefty business background. Sure, Helvey is well-funded...that's it. Compare Ed Powell's biography to that of Jay Helvey.

Powell is heads and shoulders above Helvey as far as being qualified to run for the 5th District Congressional seat.
Foxx, Robinson, Powell, and Broyhill are all great, conservative Republicans. Helvey's campaign chairman helped Bowles try to defeat Sen. Dole just last year! How can Helvey claim to be such a "great conservative leader" when he has these same people chairing his campaign? To answer your question--no, Krispy Kreme is not a Democratic corporation, but their CEO is an avid supporter of Bowles who's running against a true, great Republican N.C. political leader in Richard Burr.
