democrats. but with just one week to go, we ve already added 25 races to our potentially vulnerable list overall. 18 on the republican side, 7 on the dem side. there s some reasons why we re seeing this battleground start to expand. let me start with michigan. the 6 and 7th districts there we ve added to this list. with the republican gubernatorial nominee cancelling all ads in michigan this week except in the detroit area with one week to go, the party seems to be conceding defeat at the top of the ticket. the flint water crisis has just been devastating to the republican party statewide. so what has that done? it s a trickledown effect. it means two republican incumbents in michigan are vulnerable. there are three on the list. now it s up to five, all thanks to the top of the ticket debacle. we ve also added two of the at-large districts. when we say large, the geographically largest. alaska, montana. in good democratic years, both of these races do come into play
