Americans' interest in a successor to John Paul Stevens is gathering mostly around Merrick Garland and Elena Kagan, if you believe Google searches are a measure of our collective curiosities.

The popular search engine's list of "hot searches" in the U.S. shows Garland is now the No. 3 top search, with Kagan at No. 4. The "hottness" of both is rated "volcanic," the highest rating from Google Trends. It's not often that an appellate court judge and the solicitor general are buzzworthy, so it's worth noting on the rare occasion it happens.

None of the other names floated as potential replacements made Google's list -- so far.
