Grand Coalition with Liberal Democratic, Progressive Conservative, Agrarian Progressive, and Solidarity & Justice
[1] A group of Southern MPs from the Progressive Party entered the Farmer-Labour-led coalition in protest of the national Progressive Party's failure to respond adequately to rural issues.
[2] The Progressive Conservative Group was a faction of centrist MPs from the Conservative Democratic Party led by Elliot Richardson and Charles Mathias who broke from the party line and allied with the Liberal Democrats in protest of the hardline conservative policies of CDP leader James Buckley.
[3] Sir John Fitzgerald Kennedy had assumed the title the 2nd Duke of Barnstable after inheriting it from his father after his death in 1969. Upon being elected Progressive leader in 1971, Kennedy suspended his peerage and was elected to the House of Commons under his given name. He later reassumed his dukedom after his retirement.
[4] Though George Bush's Conservative Democratic government was a majority, it was a tenuous one: the centrist and right wings of the party were bursting at the seams, causing an internal conflict which ultimately led to the party splitting up. After the dust settled, two major factions emerged and formed parties: the Progressive Conservatives and the Democratic People's Party.
[5] In late 1989, the Progressive and Farmer-Labour parties finally settled their disputes and merged to form the Progressive-Farmer-Labour Party, with Progressive leader Joe Biden as party leader and Farmer-Labour leader Max Baucus as deputy leader.
[6] The ministry of Sir John McCain, a political outsider with an compelling record as an Admiral in the Columbian Navy, was initially a welcome victory for the DPP, but his partnership with the Civil Liberties League and his apparent centrism on social issues led to his ouster by party insiders. Today, McCain sits as an independent member of the House of Lords.
[7] Biden, a former Prime Minister, was elevated to the peerage as the 1st Count of Wilmington after his resignation. After he returned to the leadership of the Progressive-Farmer-Labour Party, he suspended his peerage and returned to the House of Commons as Sir Joe Biden. After he retires, it is expected that he will again assume the County of Wilmington, with his grandson, Robert Hunter Biden II, as his heir apparent.
[8] Although they may not be formal members of the coalition, it seems clear that PM Joe Biden has been holding meetings and engaging in discussions with leading members of the Democratic Republican Coalition, including party co-leaders Dennis Kucinich and Justin Amash.
[9] The Democratic Republican Coalition was formed in the late 1980s after several anti-monarchist parties and organizations united. Its members are free to vote however they wish (with various factions existing within the coalition) except on bills regarding the status and power of the monarchy. Although most say it is still too early to speculate, the DRC's close ties to the Biden government have led some to question whether the American monarchy is nearing its end.
This is based on my post about the cabinet of Prime Minister Sir Joe Biden, which you can find here:
