Political activists have been hitting the streets in parts of the Capital ahead of tomorrow's poll where the residents of Cardiff South and Penarth will decide on their next member of Parliament.
The seat has only ever been represented by two men since the Second World War - the longest serving was former Prime Minister Jim Callaghan, first elected in 1945. Following his retirement, Alun Michael retained the seat for Labour in 1987.
The by-election was caused by Mr Michael's desire to become South Wales Police Commissioner.
The constituency is the largest in Wales in terms of population and encompasses the post-industrial areas of Butetown, Grangetown, Splott and Rumney in the south of the city along with the more affluent Penarth and Llandough in the Vale of Glamorgan.
Labour Candidate Stephen Doughty was emphasising his party's determination to tackle the profits of large energy firms and appoint an energy regulator, while Conservative Craig Williams said the grasp his party has on the economy means he is the right choice.
Plaid Cymru's Luke Nicholas said bringing troops home from Afghanistan was a priority for his party and the Liberal Democrats, who came 3rd in 2010 were claiming people understood the influence the party has in government, Their candidate Bablin Molik declared that the party had learnt from the poor result for her party in the capital during May's local elections.
