Yeah, that's been a common problem with polls in the past. British polling just ran into the problem on a major scale decades after everywhere else.

A "realigning" election is generally considered to be one where the political climate changed. Just because the other party wins an election or there is a third party bid doesn't mean that it is such an election. Remember, most third-party bids have been single-issue campaigns.

In the 20th century, the only election considered to be unquestionably such an election is 1932. The only other one commonly cited is 1968.
