More like he knows he is fucked in NH with it being just a few days away and Bernard and Booty are likely eating his lunch there too. 538 has him as a distant third there now. May as well focus somewhere he might be able to make a dent since it's not for 2 weeks. They are still rating him as #2 in Nevada despite their model completely torpedoing him.
Problem is, a bad placing in NH makes the job even harder in NV. And it's a caucus!
