Campaign bus

[1] In the UK, they are shared by reporters, political commentators and a politician, usually a party leader, to give them all access to each other as they traverse the country making speeches and other engagements during a general election campaign.

The use of the campaign bus began at least as early as the 1940s, when The New Republic reported that 1948 presidential contender Thomas E. Dewey was "waylaid... in his campaign bus" by a charmed female admirer who "told him she would vote for him because he was 'so pink and pretty'".

[3] John F. Kennedy's "Alliance for Progress" theme was coined on board a campaign bus travelling through Texas in 1960.

[2] The battle bus was a significant feature of the 1987 general election as David Owen and David Steel of the SDP–Liberal Alliance each crisscrossed the country in matching battle buses,[6] each painted bright yellow.

[10] In the United Kingdom, John Major "adopted the old-fashioned practice of addressing the public from a 'soap box' erected outside his campaign bus".
