The discussion centers around the RNC's aggressive tactics, particularly robocalls accusing Obama of terrorist associations, which McCain has publicly endorsed. Critics argue that McCain's statements misrepresent the facts and reflect a desperate campaign strategy aimed at securing electoral votes in battleground areas like Maine. The conversation raises concerns about the ethical implications of such smear tactics in politics, questioning whether they cross the line into defamation. While some suggest Obama should pursue legal action for defamation, others point out the challenges public figures face in such cases, citing the high threshold for libel and slander claims. There is a sentiment that McCain's campaign has alienated him from former supporters and that he is perceived as a candidate willing to compromise integrity for electoral gain. The thread concludes with a broader critique of political smear tactics and their potential consequences for democratic discourse.
