The NRCC has set up a page to contribute to all of their contenders whose races have gone into overtime, so to speak: Still Counting.
They say the vote totals on the page will be updated as quickly as possible. The short version is Renee Ellmers (NC-2) leads by more than 1,600 votes; Blake Farenthold (TX-27), Randy Altschuler (NY-01), Ann Marie Buerkle (NY-25), Andy Vidak (CA-20), and Joe Walsh (IL-08) lead by several hundred votes each; David Harmer (CA-11) and Andy Barr (KY-06) trail by several hundred votes each.
