Some of the memorable elections from past years
There were unusual political posters in the 1920s and 1930s, a botched redrawing of the constituency boundaries in 1977, the €50m electronic voting experiment that went horribly wrong, and Fianna Fáil's fight back in the final days before voting in Election 2007.
History of political posters - Watch the report
Nowadays, posters tend to be flattering pictures of candidates.
However, when the State was founded the parties used posters to undermine each other and poke fun at the leaders of the rival parties and their policies.
Here are some used by Cumann na nGaedheal, which later became Fine Gael, in the 1920s and 1930s.
Election of 1977 - Watch the report
The extraordinary election of 1977 gave Fianna Fáil and Jack Lynch their biggest ever majority.
The promise to abolish domestic rates and car tax helped them win.
However, it was a botched redrawing of the constituency boundaries by Jimmy Tully aimed at keeping Fianna Fáil out of office that turned a swing into a landslide.
Electronic voting experiment - Watch the report
It was an attempt to get away from what Bertie Ahern said was making us the laughing stock of Europe - using pencils and paper to count votes in what is the computer age.
Instead, we were to have electronic voting to give a complete constituency result just as soon as the polls closed.
It was an experiment that went horribly wrong and cost the taxpayer €50m.
A look back at Election 2007 - Watch the report
During the last General Election, early opinion polls indicated that a change of government was on the cards.
The infamous cash dig-outs for Bertie Ahern was one of the big stories of the time, but Fianna Fáil fought back, rising in the polls in the last days before the vote.
They questioned whether Fine Gael and Labour could be trusted with the economy and Bertie Ahern blamed the media for his troubles.
