Many more conservative and centrist National supporters preferred Muldoon's more authoritarian and interventionist policies over the free-market liberalism promoted by Douglas. However, the new National Party Finance Minister, Ruth Richardson, strongly supported Rogernomics, believing that Douglas had not gone far enough. Her policies—dubbed "Ruthanasia"— encouraged two MPs to leave the National Party and form the Liberal Party. Richardson's views also met with considerable opposition within the National Party Parliamentary Caucus and for a time caused damage to the party's membership base.
