It looks like national Republicans may be giving up on both GOP Senate candidate Mike McGavick and GOP Senator Conrad Burns. McClatchy Newspapers reports today that neither the NRSC nor the RNC have booked any ad time for McGavick. Meanwhile, today's Montana Missoulian says that the NRSC hasn't spent a cent on ads for Burns since August 7. Not surprisingly, the NRSC in both cases denied giving up on its candidates.
