For a start, nearly everyone recognises that the far left and far right come back round and meet round the back. Communism and Fascism have for more in common with each other than either has with mainstream democratic politics even on the "same side" of the political spectrum. And present day BNP activists are astonishingly similar in many ways to the Militant Tendancy activists I recall having to deal with in my student days.
A more sophisticated way to look at different views is to consider two dimensions: one way of doing this is for "Left to right" to be defined by what degree of economic liberty you support - with more economic freedom on the right - while "Up and Down" is represented by your degree of social liberalism (usually shown with authoritarians on the top and social libertarians on the bottom.)
Two good websites which discuss this subject are Political Compass and Political Spectrum both of which discuss the placing of major political figures and include tests to check one's own.
Here is how "Political Compass" chart world leaders:

My current score on the Political Compass test is -
Economic Left/Right: +4.62
(where -10 is extreme left and +10 extreme right)
Social Libertarian/Authoritarian: -2.82
(where +10 is extreme authoritarian and -10 extreme social liberal)

This makes me a centre-right moderate social liberal, and as such, surprisingly rare for a modern politician in being in the quadrant of the political map which supports both economic and social liberty. You'll note that there is nobody in this quadrant in the international list. On a UK chart I would probably be sharing the quadrant with David Davis, Peter Lilley, and possibly some of the "Orange Book" Lib/Dems. (I come out in the same quadrant, though much closer to the centre point, on the "Political Spectrum" test.)
If you compare the two graphs you will also see that I come out as both far more liberal, and apparently marginally to the left, of Gordon Brown. But considering the present Prime Minister's propensity for supporting ghastly authoritarian measures, and clobbering the poor, (see previous post "Whom the Gods would destroy") for a Tory candidate to be more liberal and left wing than the present Prime Minister is less surprising than one might think!
