This would definitely seem to be the case when looking at Frodo and Bilbo… but Pippin seems to be more easily influenced. I think that when he drops the stone into the well in the mines of Moria, it was probably because of the ring's influence on his mind. That's the way I see it anyway… If that's the case, then it wouldn't be hobbits, but Bagginses, that have a great resilience to the Ring.
However, Pippin never expresses any sort of desire to have the ring, unlike many of the other characters, and neither did the other hobbits, so maybe they are stronger aftrer all…
Perhaps it is something to do with desiring power. Hobbits are quiet folk, certainly not the sort to want to rule Middle Earth- all the other races, the men, the dwarves, the elves, even wizards like Gandalf, are much more power hungry than any hobbit. I think this probably has something to do with it.
