This has been a TV-dominated election - and not only because of the long-overdue televised leaders' debates.

The first one, on April 15, transformed a campaign that had previously threatened to kill much of the electorate by boredom under a bombardment of claims and counter-claims about nation insurance rates.

Many electors discovered for the first time that the Liberal Democrats are led by someone called Nick Clegg. His 'I'm not like the others' performance woke many people up, and for a while it seemed he might take the country, and the election, by storm.

The second TV debate on April 22 was also of pivotal importance. Had Mr Clegg been allowed to run away with it again, he might have been able to push his party's poll ratings up into the high 30s and go on to a landslide election victory akin to that achieved by the Liberals in 1906.

This time, however, Mr Cameron gave as good as he got, and stopped the rot. As with the first one, Mr Brown got the lowest ratings in just about every poll conducted on the debate.

April 28: Who will ever be able to forget Mr Brown's 'Rochdale moment'? His car crash of an encounter with pensioner Gillian Duffy provided unforgettable TV that will be shown again and again in future election campaigns as an illustration of how in just a few seconds months of preparation can be turned into a smoking ruin.
