Always seems to me that there is no adequate definition of left and
right in politics.

There is a group that is trying to introduce a second dimension to
political descriptions:

In essence, they suggest using left - right strictly to describe the
economic policies, and they superimpose a second dimension that measures
the degree of authoritarianism. Therefore, you can have authoritarian
or libertarian governments at either extreme of the economic spectrum.

The above web site also has an interesting test, where you can evaluate
your own views to see how they would fit into their definition, and
compare the result to many past and current political leaders.
