For believers in a strong political party structure, there's nothing wrong with this stance. A party by its nature brings together people with a certain range of opinions. Often those opinions must be modified or softened in order to maintain the integrity of the party. And that's vital if a party hopes to exert influence in government. The Liberals figured this out years ago.
Power is gained through a strong party.
If a choice must be made, principles will always take a back seat to the party. In fact, party principle ends up becoming the pursuit of power. This is an especially hard concept for Alliance members, most of whom came into politics because of a conviction that the way politics is practised in Canada must be changed. Combine that with the instinctive suspicion of politics and bureaucracy held by conservatives such as those who make up the Alliance, and you have a surefire recipe for party disaster. They don't have much patience with concepts such as party discipline or solidarity because that's precisely what they see as being wrong with the Canadian system.
