You won't be sorry.
Incidentally, and moderately a propos, I am surprised that discussion of the fact the Republicans have put up Alan Keyes in Illinois have not referred to the fact that, apart from his desire to disenfranchise lesbians and gay men on the grounds that they are not able to control their impulses and are therefore not fully adult, he believes in at least discussing the reintroduction of debt slavery. That's right - he is an African-American who wants slavery legal again.
Words fail me.
