I don't think that it would change the outcome of the vote (unless it's very close to begin with) but I do think that it could close the gaps when the percentage of the vote is massive.

It would probably have more of an effect when there's lots of people up, because if your favourite was currently most likely to be evicted, their fans could group together to vote for whoever had the second most votes, instead of scattering their votes.
