Front is also used by the left - Front Popular - and I think they were trying to play with that back when they named the party. It doesn't mean "war" in this context, it simply means a common side to face something else. It is frequently used when two or more parties join together temporarily. Radical relates to root, not extremism. Extremist might be the opposite of radical, depending on the context. There's nothing in your list that suggests extremist positions. Far-right has a general negative connotation, so it is not the same than saying Clinton is left of Trump. Le Pen is right of most in some areas, left of most in others. THAT is the description no one would complain about.
