I will mention again that a shift of a half point is nothing to write home about. Aything within a couple points at this point is essentially a tie. So lesson: Democrats shouldn't go head-over-heals over prospects in Arkansas and Wisconsin. They are only fractionally better than they were yesterday. For the same reason, Republicans shouldn't get discouraged on either of these races.
Remember that these are projections based upon if the election were happening today. If the election were held today I would have the Republicans picking up 4 Senate seats and the Democrats picking up a net of 1 Governorship. My Current toss-up range (±3%) is as follows:
Senate: GOP +1 - +8
Governors: GOP +2 - DEM +4
On July 18th, my range was as follows:
Senate: GOP +1-9
Governors: GOP +3 to DEM +2.
