A study done by the Project for Excellence in Journalism showed that MSNBC had less negative coverage of Obama (14 percent of stories versus 29 percent in the press overall) and more negative stories about Republican presidential candidate John McCain (73 percent of its coverage versus 57 percent in the press overall). MSNBC's on-air slogan during the week of the 2008 presidential election, "The Power of Change", was criticized for being too similar to Obama's campaign slogan of "Hope and Change". After the election, conservative talk show host John Ziegler made a documentary entitled "Media Malpractice... How Obama Got Elected", which was very critical of the media's role, especially MSNBC's, in the election. While promoting the documentary, he had an on-air dispute with MSNBC news anchor Contessa Brewer about how the media, especially MSNBC, had portrayed Sarah Palin.
