marrow&...

Just two simple questions, i hope you will easily help me.. ok, they're
quite different, but i'm coming back home after an alchoolic night and a
political day...

1) I was thinking about an italian translation of "marrow" and, well,
everything's ok but the title!
I searched on a dictionary but i'm not sure that what i found is a good
translation... can you find some synonymous to define what's the meaning of
marrow??

2) What's the party joining Kucinich presidential campaign? and what could
be his real impact on american next election?

                        Thanks,
                                                            Marco
