This so-called "negativity" on the part of Obama is quite mild compared with Bill Clinton implying Obama doesn't love America--in his "There are two candidates in this race who love this country," referring to McCain and Hillary. It is quite mild compared to Hillary saying she and McCain has passed some illusory "commander-in-chief" test, but maybe Obama hasn't. The Clinton campaign has been running on slime since before the Ohio and Texas primaries. What Obama is doing is not slime.
