Tighten White-space usage for Nomination "View details" with float:right

Tighten vertical white-space by allowing Nomination "View details" results to `float:right` with the result.  The `margin-left:0.5em;` ensures there is a single-character spacing between the result and view details.  The `margin-top:0.2em;` is a kludge; as variants of `vertical-align:baseline` don't seem to be working and it looks odd unless the baselines are matching.  Help/suggestions appreciated!
