Conservative: Conservatives in the 19th century we see as those that tried to limit reforms to preserve the old order. When the threat of revolution got high enough, the conservatives would seek to give some ground in order to preserve the rest. This new Status Quo would be the one that the Conservatives would now seek to defend. The result is that conservative members of the upper house never support the removal of current reforms. However, they will not support the extension of reforms either. However, under conditions of high militancy some Conservative members of the upper house will break ranks and support either social or political reform.
Reactionary: Well, the name sums it up. Reactionaries don’t like the way things are and instead hanker for the good old days that probably never existed anyway. Reactionary members of the upper house never support the extension of existing reforms and instead support the removal of all reforms.
Liberal: We tie liberalism and political reform together. Liberalism as an ideology is all about seeking reform of the political system. Thus, members of the upper house who have a liberal ideology always support the extension of political reform. Like conservatism, some will support the extension of social reform but only under conditions of high average militancy.
Anarcho-Liberal: Anarcho-Liberals are angry liberals. They will actually seek to prevent the extension of political reforms, because they would much rather overthrow the government than reform it. They also support the rolling back of social reforms, because the government should be as small as possible.
Socialists: The socialists are the opposite of the liberals. Socialists, like their name implies, seek social reforms always. They never want to roll back reforms, and some will support political reform under conditions of high militancy.
Communists: The people who are dedicated to protecting the workers from everyone except the communists. They always support the removal of political reforms and always support the advancement of social reform.
Fascists: Do not support any move on reform unless there is a fascist government. Then they behave the same as communists. Essentially, in opposition the fascists are spoilers in the political system, seeking to force gridlock to allow a fascist revolution.
