Hannity is not to blame. He is a conservative, but he is still a journalist. He was the first interview Moore did after the Washington Post smear story and he asked fair questions. Moore came off as evasive. Moore should have been better prepared.
Moore needed to get the full truth out right away. His wife is 14 years younger than him (They were married in 1985). When Moore was 30-ish, fresh out of the military and a young lawyer, he probably did date some young women in their late teens or early 20s. In the Alabama in late 1970’s, that probably wasn’t considered inappropriate and certainly not illegal. For most of human history, that wouldn’t have been considered unusual or inappropriate.
In that first interview, Moore needed to clearly acknowledge what was true, and clearly deny the smear of illegal activity.
Also, Moore needed to be out on the campaign trail the last few weeks, rather than hiding and letting Trump campaign for him from beyond the borders of the state. In the end, if 25,000 more conservatives show up to vote for Moore, he is the Senator, flawed or not flawed. An active campaign in the last few weeks would have accomplished that.
Hannity is no journalist. Believing that is an error that many folks in this forum make.
Hannity is an entertainer, an opiner , a gadfly.
Generally, he talks out of his ass. I would be careful about putting any faith in his reporting.
