You knew the GOP would run someone against Patty Murray, and there’s worse they could do than Chris Vance. I’m not sure that I’d go so far as to call him a sacrificial lamb, but it’s tough to see his path to victory. As Andrew mentions in the linked post, he has lost for Federal and statewide offices.
If Patty Murray could hang on 6 years ago, the seat is probably safe in a presidential year with Trump or another Bush at the helm. But I try not to forecast these things, so who knows?
Also, color me unimpressed with debt as a central campaign issue. (a) It’s not really as big a deal as political insiders make it out to be. (b) Deficits have gone down every year under Obama. Deficit and debt aren’t the same, but those lower deficits and surpluses will lead to debt being even less of an issue politically and policy-wise. (c) Much of our debt is due to wars and tax cuts happening concurrently under politicians Vance supported. (d) Much of the rest of the debt is due to the economic collapse brought on or exacerbated by GOP policies. So it’s tough to see how an anti-debt platform translates into votes.
