It's just four days since Barack Obama became president-elect and already the knives are out. On Cafe Press, where capitalism meets the First Amendment, more than 18,000 "Impeach Obama" items are now on sale. On Facebook, you'll find 17 pages of groups agitating for impeachment, the largest of which already tops 6,000 members. Comments on political web sites large and small are so highly charged, I can't bear to link to them. Wonder if any of those fine Americans realize Obama stood up for our outgoing chief executive, saying talk of impeaching George Bush was "unacceptable".
