Republican leaders and conservative pundits have spun Democrat Kathy Hochul’s upset win in New York’s 26th Congressional District as exceptional – with peculiar ballot lines, Tea Party independents, quality of the candidates, and Democratic message discipline.

It is an advance indicator of a sharp pull back from Republicans, particularly those in the House.
