Another point on polls

POLL: Ernst Breaks Away –

If you follow the links and read through to the middle of the Des Moines Register article, you find that the poll which they would have determining the outcome of the balance of power is a poll of only 701 people.

The margin of error is 3.7%, so if the Democrat is behind 7%, it would be within the margin of error for him to have a slight lead.

And 3.7% sounds a little low for the margin on a poll that tiny.
