I'll personally be voting for Jack. Honestly Mike Foley seemed perfectly acceptable too and I don't think he'd do a bad job, but I've attended Jack's matches for years now and he's always been very involved and hard working.
No podcast interview puts the other two off my list already for the most part, though the mere mention of an association with Prod Optics kills any chance of me voting for Paul Hyland. Manny Bragg - honestly I don't have a feel for him as a candidate currently (and realistically - I'm too lazy to go digging around for info myself), though I do think it may be hard to beat his name recognition among the membership at large.
