[Eorl of Rohan]

Pippin? Not really. The only thing that he succumbed to the desire to look int he Palantir was becuase he handled it first. Didn't Gandalf say to merry that it might have been worse if it was him who picked it up first?

AFter all, since Pippin was frank and simple, he was able to get out of the tight situation pretty well.

Those who didn't vote for Pippin voted for Aragorn, but I don't think so. He was the only person who was able to look at Galadriel in the eyes at her temptation.

The ring didn't only give power and glory, it promised to give whatever the person wanted, so gimli or legolas is as likely to fall victim as Aragorn.

I reach the conclusion - Mithrandir would fall next. The maiar were forced to walk in human flesh, and lost much as thei power and wisdom. Even without the ring staring at their face, Curunir and others fell one by one. Mithrandir, beseted on all sides and forced into a hopeless battle, would need the ring badly. He admitted himself many times.
