Well, no, actually. For instance, Doctor Who Magazine does the poll annually, and Tom Baker has been winning since the 1980s, losing only twice through 2006,to Sylvester McCoy in 1990 and David Tennant in 2006; I don't know what happened last year. The current Doctor has an obvious advantage, but not a lock.As Captain Dago noted, the current Doctor always leads the poll. Even back in the days before the internet.(How on God's green Earth is David Tennant leading this poll?)
