So, pretty much every Senate election since 2006 has been a wave election for one party or the other. Thus, I was curious to see what would happen if each election had a wave the went in the opposite direction.
First installment: 2006
Indiana and Connecticut were excluded from this analysis, due to the unusual situations in both of those states. Kerry won the remaining states by 0.3% (2.8% more Democratic than the nation), while Democratic Senate candidates won overall by 13.7%. Thus, 10.9% was subtracted from the Democratic column and added to the Republican column:
Republicans 60 (+5)Democrats 40 (-5)Closest races:
