One could debate about whether it should be 50 or 55 or 49. The principle that I disagree with was allowing the governing party to prolong the election campaign based on its own decision. The principle that we've held to since 1974 is that of a relatively level playing field. If you have the authority to extend the election campaign, and you happen to have a lot more money than your competitors do, you are, through that decision, potentially creating an advantage for yourself.
Money doesn't buy elections, and we saw in 2015 that the party with the most money was not re-elected, but it's not consistent with the principle of the level playing field to allow the government to simply extend. It was quite a bit longer than two months, as I recall. Somebody around the table should know how many days it was exactly.
