Early likely casualties, based on admittedly incomplete tallies... Shane Ross, Katherine Zappone, Paul Murphy, Joan Burton.
Labour look an old, spent force. Solidarity-PBP-whatever-we're-called-this-week look like being nearly wiped out. Greens look good for big increases. Soc Dems - maybe one or two seat gain? Gary Gannon in with a long-shot shout, but much depends on where Mary Lou McDonald's second prefs go. She's running a 1.5 quota, and her transfers seem to be going on gender lines. Core SF voters traditionally plumped and didn't transfer. Will their new-found voter 'punish' FF and FG with only a 2 or 3? Could see the big two taking final seats based on transfers in that case. But I have a feeling that transfers won't be so easily guessed this time.
I have a hunch, too, given SF's success with the 18-30 voter, that we've seen the last Saturday vote for another century! Everything Vardkar turned to went sour. It'll be some legacy to lead the party to this disaster, not bring in a running mate (first FG leader since FitzGerald to fail) and hand either ministerial seats or lead opposition status to SF.
Edit: I can see the SF 22% FPs being somewhat false. Several candidates are polling far higher than this - mid-thirties and higher - and in the ordinary run of things that would bring in a running mate. Most don't have one, so these votes will spread, and be lost. Can't work with incomplete figures, but these big dogs could be inflating the SF poll by 5% or more, leaving them with something closer to 17% in effectual votes, giving them seats somtwhere in the high twenties. Pure guesswork at this stage, though.
