People in politics, such as Bob Hawke have said in their personal dealings with Tony Abbott, that he's actually quite a nice bloke. And so have people involved in community organisations in the northern suburbs of Sydney that he involves himself in. Apparently a really dedicated grass roots community bloke who rolls his sleeves up and gets involved. But on the flipside, these people concede that he is obviously a bit nutty and as such, wasn't PM material. He didn't earn the nickname 'The Mad Monk' for nothing. And people in the political sphere often have a different persona than they do in their personal sphere. He wasn't necessarily a perfect fit for Liberal Party ideology either. He did delve into relationships with ALP-right personalities early in his political dealings and was urged by some to join. But he felt it wasn't the party for him. Abbott was actually ideologically closer to DLP leanings in his formative years and has said he followed B. A. Santamaria closely.
ScoMo I've never really heard the same endearing side. Most accounts seem to be more that he's a bit hollow and you don't know what he stands for. And he certainly can't read a room. Completely tin eared.
