Put another way, in both the House and Senate, it’s the wave versus the map,” Charlie Cook, the founder of the Cook Political Report, retorted a day later. Even before Trump took office, members of both parties agreed that the House majority would be up for grabs. Those 26 seats Democrats are defending include five in states that Trump won by more than 18 percentage points — plus five more in states he won by smaller margins. In 2016, Republicans won five of seven races the Cook report rated as toss-ups. In 2012, Democrats won eight of 10 toss-ups.
