There is a rare sense of mystery overhanging Donald Trump’s campaign rally tonight in New Hampshire, the latest in a series of WWE-style performance pieces that have become increasingly predictable. One can expect the usual grievances about Hillary Clinton and Ilhan Omar, immigrant invasions and fictitious status updates on the border wall. But Trump, who lost the Granite State in 2016 by less than 3,000 votes, will also have a delicate political drama with which to contend: whether to ruffle state party officials and throw his support behind his former campaign manager, Corey Lewandowski, for Senate.

So far, Trump hasn’t not endorsed Lewandowski, and in fact, recently praised him as “fantastic,” “terrific on television,” and a family man. “I will say this, if he ran he would be a great senator,” he told New Hampshire Today on an interview taped Wednesday. ”If he ran and won he’d be a great senator. He would be great for New Hampshire, he’d be great for the country. He has got a tremendous drive and that drive would be put to the people of New Hampshire's benefit and the country's benefit.”

But the New Hampshire GOP has plenty of reasons not to want Lewandowski to run. For one, they already have two potential candidates who could challenge two-term Democratic senator Jeanne Shaheen for her seat, including Bill O’Brien, the former state Speaker of the House. (The other is Don Bolduc, a retired brigadier general.) More important, however, virtually nobody seems to like Lewandowski, who comes with extensive baggage and no elected office experience. “He adds nothing to the ticket and doesn’t help the president or the ticket in any way,” New Hampshire strategist Dave Carney told Politico. “Corey is a political hack. Political hacks make bad candidates generally.” Other Granite State power brokers agreed, including former GOP senator Judd Gregg, who called him no less than a “thug” and his potential nomination an “outrage.”

With Trump descending on New Hampshire tonight, it’s an all-out war between pro- and anti-Lewandowski factions to sway the president before he opens his mouth:

Republicans on both sides of the divide have launched a campaign to sway Trump ahead of the rally. In a gambit aimed at securing a presidential endorsement, David Bossie, an ally of Lewandowski’s, released a poll on Tuesday showing that he would become the front-runner if he were to run and that Trump’s support would solidify his standing.
