Indeed there is a position:relative misplaced.
If you have a moment you can try the following change to index.css:
#poll_options .results {
display: inline;
}
#poll_options .results {
position: relative;
}
This should fix it.
ETA: note for whoever will apply the patch, the position:relative on the bar can be removed.
In the meantime, you may want to remove this block as well:
.statsbar .bar {
max-width: 12em;
}
that is useless and makes the bar shorter than it should be.
