Daily Kos Elections Polling Wrap: Democrats hold reasonably strong hand in new Senate polls

While there was quite a load of data on the presidential campaign beat today (much of the national polling, incidentally, coalescing around the same result'Obama +1), today was really a day for the battle for the balance of power in the U.S. Senate to take center stage.
