Prime ministers defeats

Today I am talking about prime ministers losing their seats while there have only been two. Stanley Bruce had a terrible goverenment with a disunited nationalist/country (predecessors to libs and nats  goverenment) his seat of flinders was lost in 29 to labor. In 1974 and 2007 a minor party dlp in 74 and democrats in 2007 were wiped out so the leader was beaten. In 1990 nationals leader Charles blunt lost Richmond to labor after preferences. The democrats weren’t the biggest shock in 2007 when John Howard who had represented benelong since 1974 lost to labor in a big shock, this was after a lot of preferences. If Rudd loses he will be the first labor prime minister or leader to lose his seat, this seems unlikely but at this point the polls don’t add up but this didn’t even happen at state level in qld and nsw last time. On a similar topic Rudd lost in 96 to the libs the first time so it isn’t impossible.
