If a candidate attacks another candidate for being too negative, isn’t that….negative?

Hillary Clinton and Barack Obama haven’t crossed paths
yet during their weekend barnstorming across Pennsylvania, but they
have invoked each other’s names at virtually every whistle-stop during
the final blitz before Tuesday’s primary.

Each candidate says the other is unfit to lead the country.

Clinton has attacked Obama for his recent comments about some
small-town Americans, his heath care plan and his relative Washington
inexperience. Obama has countered by taking aim at Clinton over her
acceptance of money from political action committees, her health care
plan and her Washington experience.

But the most oft-repeated charge — the one mentioned at virtually every stop — is negative campaigning.

That that is all they have in their arsenal right now, says a lot.
