via MSNBC, a somewhat surprising article given the source. They analyzed political contributions made by journalists to Federal candidates, PACs and the two major political parties. They found that of the 144 journalists making contriubtions, 125 gave to Democratic candidates or causes, 2 gave to both parties or candidates from both parties, and 17 to Republican causes. No surprise here, and although most of the contributing journalists do not cover politics, they certainly tilt overwhelmingly leftward.
"The pattern of donations, with nearly nine out of 10 giving to Democratic candidates and causes, appears to confirm a leftward tilt in newsrooms — at least among the donors, who are a tiny fraction of the roughly 100,000 staffers in newsrooms across the nation. "
A number of the organizations these journalists work for do not allow their employees to make such contributions (ABC & CBS for example), and several have changed or are examing their policies to prohibit such employee activity. Some of the organizations do allow employee contributons, such as FoxNews and Forbes magazine. There is no record that MSNBC could find of any of the journalists disclosing their contributions to the listeners or readers.
