The Party on the Left, is now the Party on the Right
In the US, for example, the Radical Right (usually hand-waved away as "the Tea Party")
No, you don't understand U.S. politics, these are two completely different, very very different things. You need to do some research and correct your article.
But let's try something. Let's make some modifications (in bold) to what Trevor and Josh wrote and see how this reads:
In the US, for example, the Radical left (usually hand-waved away as "the Progressives") gets under my skin quite easily. They are the extremist left wing, powered by emotion and only resorting to evidence or logic as a means of justifying positions they feel are right. Emotion is the impetus and driver of behavior and everything else exists to justify, validate, promote, and enforce the emotion.
How's that read?
The USA has two parties: One wants huge deficits and high taxes, the other wants huge deficits and low taxes. Anybody who insists "one party all good, other party all bad" is just a tool. As a political consultant we used to call those on both sides "yousits", short for "useful idiots".
Or I like comedian Lewis Blacks interpretation - the US is composted of the Reps, the party of bad ideas, and the Dems, the party of no ideas. Typified by a Repub will stand up in Congress and say "I've got a really bad idea!" and a Democrats will stand up and say, "And I can make his idea shittier !!!'
However, I can understand The Reg's bias. Statistically speaking, those on the extreme left are more likely to click on online advertisements, while the extreme right is more likely to respond to a TV commercial.
