No. There's no real definition of 'Liberal'. Every one of them is different. About the only commonailty is that they all dislike the Republicans.
The Republicans are well known to be 'lockstep' in their points of view.
In many ways the best definition of a liberal would be 'a compassionate conservative'. They believe in tempered capitalism, a fair market, not a free-for-all market.
Liberals do not have anything against wealth, but they do have something against poverty.
We also tend to agree that working people deserve fair compensation and that most wealthy people have not earned their wealth. That at most they work hard at sucking up all the money they can, without making much of a real contribution to society. So we don't feel guilty about taxing the wealthy.
We'd like to see a narrowing of the gap between rich and poor not an elimination of that gap. We'd like to see more of the American dream and less of European style royalty in this country.
Of course that's my opinion of what a 'Liberal' is. Talk to the next self-described 'Liberal' and you'll probably get a whole different story.
