Maybe but that doesn't make a persons perspective right. For example, bill Clinton seduced a teenager inside the White House yet he is beloved like he is some pillar of leadership. The left has an uncanny ability to look the other way concerning the moral failings of their leaders...as long as they are progressing the leftard ideology.
But what causes one person to view the grouping of Bush photos as an affectionate but misunderstood guy, and the same person to view the group of Biden clips as a 100% creep? Both show each respective person being affectionate, both show those on the receiving end being less than receptive.
I think Bush and Biden are just touchy feely guys, and some of their objects of affection simply are not. That doesn't make Bush or Biden creeps. But those who want to see one of them in a certain light can use these events as fodder to frame said person in a certain light.
