IMHO, it is POSSIBLE that Alito would get 1 or 2 NO VOTES on the nomination.. however the attempt to fillibuster WOULD result in the nuclear option being invoked...
Still a little early to count the votes (waiting for hearings)
The reason I disagree is this: As soon as it becomes clear that the Repubs have 50 + 1 (Cheney) sure votes against the filibustering, the Dims will call the Alito filibuster off, and Alito will sail through.
Until that time, some of the Dims will continue to threaten it.
