I don't have time to write about these, so let's let six pictures do the talking. The blue line is the standard trend estimate, and the red the more sensitive trend.
I've added the names of the last two polls (last three if there is a tie on the date of last interview.) This helps put the latest results in some perspective, both poll vs poll and poll vs trend.
These are relatively high resolution plots so you may need to click once or twice for full resolution.
