Because this sort of thing turned out so well for Joe McCarthy:
Rep. Spencer Bachus, the top Republican on the Financial Services Committee, told a hometown crowd in Alabama today he believes there are several socialists in the House. Actually, he says there are exactly 17 socialists in the House of Representatives.
Which, of course, implies a "list." By the way, is there any difference between this and Scarborough repeatedly playing the "socialism" card on his show every morning? Neo-McCarthyism is neo-McCarthyism, lists or not.
