No, but I mean during election day and after the election. What is the opposite of a close election?
Sorry, Antonio. By "close election" I understood you to mean one in which the result is (or is expected to be) very close:
Candidate A - 51,001 votes; Candidate B - 50,999 votes
("a close election which ended in a neck-and-neck result")
Candidate A - 55,000 votes; Candidate B - 45,000 votes
would be "a clear victory" for Candidate A
Candidate A - 75,000 votes; Candidate B - 25,000 votes
would be "a landslide victory" for Candidate A
Candidate A - 90,000 votes; Candidate B - 10,000 votes
would be "a wipeout".
Perhaps, by "the oppposite of a close election" you mean
"a wide-open election":
that is to say, one in which no-one can confidently predict the result.
You couldn't really say that, though,
after the election, at least not once the result was known, since by then the election would no longer be "open".
