Taking cues from their communications shop over at Fox News, GOP Sens. Lamar Alexander (R-TN) and Judd Gregg (R-NH) yesterday attacked the White House\u2019s campaign against Fox\u2019s unethical journalistic practices by comparing President Obama to President Nixon. \u201cLet\u2019s not start calling people out and compiling an enemies list,\u201d Alexander said, touting his days as a junior staffer in the Nixon White House as credentials for his charge. Gregg said he was \u201cfascinated\u201d by Alexander\u2019s criticism and wondered if Obama is \u201cNixon-fying\u201d the White House. But yesterday on MSNBC, top Nixon aide Pat Buchanan dismissed out-of-hand any comparison of Obama to Nixon:BUCHANAN: It is the most idiotic comparison I\u2019ve ever seen. Barack Obama won 95 percent of Washington DC, he comes in with both houses Congress behind him, the media love him, the country loves him. Nixon came in with both houses of Congress against him, he probably got 8 percent of the vote in Washington DC, the media loathed him. \u2026 I don\u2019t see any comparison between Obama and Nixon whatsoever. \u2026 [T]here\u2019s no comparison. Barack Obama\u2019s got enormous press support, he\u2019s got problems with Fox News but for heaven\u2019s sakes there is no comparison here.
