Why is it of interest to none LP members that Blair won three elections? People don't vote (well not thinking people) just for someone that knows how to win. If he didn't stand for the politics they wanted to vote for it's irrelevant; if he did they presumably chose to vote in that direction. It is history to them whatever way they voted - they will just not be interested in the internecine strife and petty jibes.
From a Labour Party point of view those who disagree with the leadership and the direction the majority is taking the party have several choices. They can persuade, by presenting a positive case, from within or they can leave and start a new party or they can wait and put their case in future party elections. What they are actually doing is making personal attacks on people who have been democratically elected and whinging. It is not a good look and certainly not an attractive one to people outside the LP. It's looks as if they would rather the LP to failed than succeeded with policies they, the minority, don't agree with.
