When the election was called, it was expected to be anticlimactic, with Klein cruising to his fourth straight majority, the tenth for his Progressive Conservative Party.
Shortly after the drop of the writs, Klein's mother died and all parties suspended their campaigns for several days.
In the end, the Conservatives were re-elected, despite losing 11 seats and 15% of the popular vote, having dropped to a minority position in the polls.
Dunvegan-Central Peace is the sole remaining "special" division - due to its isolation, it is allowed to have a population below 75% of the provincial average.
Lesser Slave Lake is now considered to be a standard rural division as its boundaries were re-drawn so that its population is slightly above 75% of the provincial average.
Leader: Ralph Klein In the 2001 election, the Progressive Conservatives recorded a result that was comparable to those achieved in their years of dominance under Peter Lougheed.
This result was achieved due to a resurgence of the party in Edmonton, where the Tories won a majority of seats for the first time since 1982.
On April 8, 2002, Doug Griffiths retained the Tories' seat in Wainwright in the only by-election held since the 2001 election, albeit with a substantially reduced plurality.
The Tories lost only one seat since the 2001 election, after Edmonton-Norwood MLA Gary Masyk crossed the floor to join the Alberta Alliance.
Leader Nancy Macbeth even lost her own seat in Edmonton-McClung - she resigned days after the election and was replaced by Ken Nicol, the Opposition's sole representative outside the capital.
External link Leader: Brian Mason In 2001, the New Democrats were unable to claim Official Opposition status from the floundering Liberals, but Leader Raj Pannu managed to hold the party's two existing seats—Pannu's own in Edmonton—Strathcona and Brian Mason's seat in Edmonton Highlands (later merged into Edmonton Highlands-Norwood).
Pannu resigned the leadership in July 2004, with Mason filling the role of interim leader before being elected to that position in September 2004.
Leader: Randy Thorsteinson The Alberta Alliance was registered in October 2002 and held its founding convention in February 2003.
Its leader, Randy Thorsteinson had led Social Credit through a modest rebirth before quitting that party in April 1999.
The party's sole MLA, Gary Masyk (Edmonton-Norwood) crossed the floor from the governing Progressive Conservatives on June 29, 2004.
External Link Leader: Naomi Rankin The Communist Party nominated two candidates in the 2001 election, who combined for 117 votes.
