Robert Draper writes at The New York Times:
For an at-risk Republican senator this fall, to back away from Trump is, by extension, to snub his millions of die-hard loyalists, the one group of party voters that is sure to show up on Nov. 8. But to go all-in for Trump is to take leave of your Republican bona fides and embrace life as a Trump Mini-Me — a gamble that not a single Republican senator up for re-election this fall appears to have the stomach for.
None of this seems to overly concern Trump. When I asked him recently whether the party’s maintaining its majority in the Senate meant anything to him, he replied: “Well, I’d like them to do that. But I don’t mind being a free agent, either.” Trump has shown similarly little interest in helping his party’s committees build the sort of war chests typically required in a campaign year. After winning the presidential nomination on a shoestring budget and with fewer paid staff members than the average candidate for governor, he has been visibly reluctant to help build much in the way of national campaign infrastructure, sending a clear message to his fellow Republicans: This fall, you’re on your own. As Ryan Williams, a strategist with the 2012 Romney presidential campaign, told me: “Traditionally, the nominee has a robust campaign that absorbs the R.N.C. effort and works in tandem with the down-ballot campaigns. We did that with Romney in 2012. This time around, there’s a complete void at the presidential level. Trump’s trying to play a game of baseball and hasn’t put out an infield.”
