As Cruz heads to the Republican Jewish Coalition’s spring meeting here, he’s about to encounter a group of donors that, in another cycle, would have already been enthusiastically committed to the likely Republican nominee. But this time around, many are burned out after having already supported multiple other candidates who didn’t last, and now they’re considering sitting out the primary entirely.

Cruz is going all out this weekend in an attempt to bring those Republicans off the sidelines, and RJC insiders say he has a real opportunity to do so. But first, they say, he’ll need to spell out a path to beating Trump — and being competitive in a general election — that convinces disillusioned donors and well-connected party activists to rally one more time, especially in a crowd where some see him as too hard-line…

It’s not that Cruz, who just notched a $32 million quarter, is particularly reliant on RJC money. But broad-based support from the RJC, a well-respected organ of GOP politics, would send a significant message about party unity around Cruz, once a party pariah who still has few friends in the Senate.

Cruz, who gave a very well-received speech at the RJC last year and spent time working the room, already counts some leading RJC members as involved supporters. Others have quietly donated money but don’t plan to be publicly or politically active on his behalf.
