“Polls have “called” elections correctly 78 percent of the time” according to that article. Just because they are more accurate than in another time frame does not mean they are accurate overall. This is an incredibly poor rate in the larger picture. Independent groups are notoriously hard to poll and they are the ones that decide elections. If it’s a landslide then of course the poll will be correct. Completely unreliable in close elections. However they make excellent time filters for news networks.
