Sen. Deb Fischer (R-NE) has taken the lead ahead of independent challenger Dan Osborn, offering Republicans a momentary sigh of relief as they look to hold on to the Senate seat that has unexpectedly put the GOP on edge. 

Internal polling conducted during the first week of October found Fischer leading Osborn 48% to 42%, giving the GOP incumbent a 6-point advantage just one month ahead of Election Day, according to a polling memo obtained by the Washington Examiner. Another 10% remain undecided or unsure.
