I want Trump to use his time & resources in states that are winnable like Nevada, NH, VA, PA & Iowa. In any event this is going to be won or lost in the Rust Belt.
Remember Pence is working up North where he is liked by Walker and Trump just said he wasn’t suppose to have won two southern states but he went there and campaigned thankfully.
I think there are some intangibles in play here. By appearing in states that are nominally hostile, he shows that his effort is not purely mercenary, and after he wins the presidency, he is going to be president of all the people,. even in states that give their electoral votes to the DEM electors.
