Expanding Senate Map Gets Pricey

“Senate Republicans aren’t just widening their path to the majority with each new seat added to the competitive map, they’re also increasing the odds Democrats will have to spend money in states beyond the top battlegrounds,” Roll Call reports.

“Faced with such a lopsided map this cycle, Senate Democrats were undoubtedly budgeting to spend in at least 10 states… But as Republicans continue to fill their candidate roster in potentially competitive races — most recently adding Rep. Cory Gardner in Colorado — it means more money Democrats may have to spend on seats not among their most vulnerable.”
