There is a point in combat, whether it's a small battle or a major campaign that an impending defeat becomes a route. Just prior to the first Presidential debate, there were indications of small movements toward Governor Romney. These were manifested in the "internals" of many polls, both left and right. Immediately after that first debate, that movement became very noticable...so much so, that the left was stridently saying that the "bump" from that wouldn't last.
Since then, there have ben two subsequent debates, one for the Vice Presidential candidates and the second Presidential debate. No one argues that President Obama didn't "do better" this time around. What is interesting, is that many on the left have been stating the "Romney bump was over." This doesn't seem to be borne out in the polls...from either side. Whether left of right, weighted or not, at best (for Obama) they have remained static....others show a deliberate, sustained move towards Governor Romney. My assessment, is that we are at that point in "the battle," just before the losing side throws down their weapons and begins to run...the beginning of the route. Governor Romney is going to win this, with over 300 electors in his column on Election Day.
