With just over a month until Election Day, most forecasts have Democrats in a strong position to hold their majority in the Senate and have strengthened their position in the last few weeks, moving ahead in close seat polling. But when it comes to the money, the Senate remains very competitive. In this analysis, we look at the money in 19 close races that the Cook Political Report has deemed “Toss-up”, “Lean”, or “Likely” races within the last month. (We’ve excluded the three-way race in Maine for analytical purposes.) The quick summary is that, by our count, the Democrats have the lead in 11 of the 19 races. If money is determinative, this is not a great position for Democrats, since of the 19 seats we analyze, 15 are seats currently held by Democrats.
