The is not enough white space actually. There are too many explicit dividing lines. These could be done away with if unrelated items were more properly separated.

For example, there is no need for an explicit line between any of the three columns, since each of those parts content is aligned to its margin; an implicit line appears anyway.

Similarly there is not enough contrast in sizes; headlines could be twice as big (char. size), and intro texts half as long (content size).

Something needs to be done about the logo. Either have it done properly by an artist, or replace it with pure text.

I'm not a graphic designer, but I have worked on UI for some time now.

If I have time I will whip up a mock-up, and even a custom CSS.

A 'centrist' is someone who's neither on the left, nor on the left.
