If the second suit is true, this is HUGE!
I have it from Donofrio himself, that the second suit is indeed real. They needed to get the NYC one filed first. DC is commin.
A prick with ears is an obamination.
If, by the "second suit," you mean the quo warranto, no, it is probably not huge.
Only the Attorney General of the U.S. has the right to file an action for quo warranto. If the Attorney General refuses to file suit, someone else can file it, but only if the district court in D.C. gives them permission to file. There already was one attempt to file a quo warranto suit in D.C. challenging Obama's eleigibility to hold office, and the court refused permission to file it. I doubt this attempt will fare better.
