The blue wave's mixed signals

When it comes to the much-prophesied “blue wave” supposedly coming November, contradictory evidence keeps coming in. On the same day a shock Reuters poll put Republicans up in the generic ballot, Democratic primary voters in Georgia turned out to support Stacey Abrams in big numbers.

The Reuters poll, touted by President Trump on Tuesday night, could well turn out to be a fluke – nobody should ever take a single poll as anything more than a datapoint to be combined with other polls. But according to the Real Clear Politics average, Democrats’ advantage was narrowing even without this Reuters survey.
