I think there is some overlap between what you and I are suggesting.
If people on the right put more weight on allegiance to a tribe, and respecting authority, I'd expect them to be more inspired by an idealist past attributed to their tribe or authority.
If people on the left put more weight on ending harm and injustice, I'd expect them to be more inspired by an idealized future in which these evils are dealt with and solved.
I don't doubt that there are really many dimensions to political ideologies, but it seems entirely reasonable to expect a lot of correlation between ideas that seem logically orthogonal to one another.
This strikes me as similar to the ideas underlying hunch.com -- that they can ask you about your preferred operating system and brand of fast food, and then predict how you'll vote or what music you'll like.
I'm not going to say that there isn't an overlap, because I suspect there is, but you'll have to explain (for example) which so many forms of identity politics, which by definition oriented around tribal loyalty, considered left-wing causes? For example, feminism, minority rights, and class consciousness? (Your average proponent of these causes are simply expressions of the more general fight against injustice, which is true to some degree, but your average skinhead will say the same thing about his cause.)
In general, I'd say that your average right-winger and your average left-winger (in American politics anyway) care the same amount about reducing injustice and harm but have radically different understandings of what constitutes injustice and harm and that's where the difference is.
EDIT: re "I'd expect them to be more inspired by an idealist past attributed to their tribe or authority." In my experience, as often as not, they are just curmudgeony.
You might be right. I'll confess to a limited knowledge of this subject :)
As for which groups have more tribal loyalty... maybe there is something to be gleaned from which have an easy time keeping their members marching in lockstep, vs which have a hard time with that.
