Before she was Martha Raddatz at ABC News, she was Martha Bradlee here at Channel 5, WCVB-TV, and she was a heck of a reporter.
But what do I know? Turns out that in 1991, while she was still working for Channel 5, she got married to a guy named Julius Genachowski, and he invited one of his Harvard Law School classmates to the wedding.

Kevin Cullen is mostly correct. There is one tiny objection. It was not Jon Keller's general role that was an issue. He did a respectable job except allowing 20 minutes in a one hour debate about Elizabeth Warren's background. A how many angels on the head on a pin argument. His newspaper commentary after the debate ostensibly giving an insider's view of the candidates in the Green Room was bit out of line. Other than that the rest of what you said holds water.
Why did Raddatz repeatedly ask probing questions of Ryan but never of Biden after the first few minutes? Is it because Biden screamed at her for half an hour, as if SHE is running for VP??!? Was she afraid of Biden after that?? Why did she allow Biden to interrupt Ryan literally TWICE PER MINUTE??!? Why did Raddatz interrupt Ryan repeatedly but rarely Biden? I have more, why don't you? This article is incomplete, at best.
I don't know why Raddatz did what she did. All I know is Rep Ryan has a dangerous philosophy in foreign affairs and women's rights. Why don't you email her and then share it with the rest of us. Otherwise we will just have to make up our minds on what was said and how much of it holds water. The President appoints Justices to the Supreme Court, executes Federal Laws, and has the largest role in determining issues of war and peace. Depending on how you answer those issues determines who you want for President.
I think she did a fine job. Next time, they should give her a pair of volume controls, each in series with the candidates' microphone. That'd teach 'em.
