RNC Nate has somehow 'forgot to add in the Monmouth poll that has Clinton up 5 in Florida or the St Leo poll. Of course Nate did remember to add in the Monmouth poll that has Trump up 8 in Iowa. Nate is looking much less credible this cycle.
they are there. The polls are sorted by weight not just age. Although the weighting is always a bit hard to figure out. There are five polls weighted higher than the Monmouth poll (which is the most recent and from a A+ rated pollster)
I'm guessing because at this point it's a statistical outlier. That could change with another poll or two.
It is because Monmouth used a smaller sample size than the other polls (i.e. higher margin of error)
