I think it was a mistake. It’s true that if Sanders hopes to get nominated he has to go through Clinton at some point. But he doesn’t need to personally attack her - there are plenty of other people who will happily attack her for their own reasons. Sanders should have stayed above the fray and reaped the rewards. By joining in, Sanders will alienate some of his supporters by appearing to be “just another politician” and, more specifically, he’ll make enemies in the Clinton camp - and he’s going to need those same people if he wants to get elected.
I wonder if the Clinton campaign intentionally tried to provoke him with the “sexist” accusations?
Bolshevik Bernie will be beaten badly. Socialist Sanders shall see stars.
Saying that campaign should be about issues and not character is not the same thing as saying that the investigation is a hoax and should be halted. Let the FBI do their job. Meanwhile lets focus on what’s important in elections: issues. I think you are right to judge the policy differences between Hillary Clinton and Bernie Sanders as not huge, particularly after congressional input. But there is a lot a president could do without Congress, including descheduling marijuana (assuming “he” can sustain a veto) and there is the the appointment power. Sanders would seem to come to office owing fewer favors (but certainly some to the Democratic establishment) So there are real differences to say nothing of the impact on future politics.
That’s “going rough”? I’ve seen playground noogies more vicious than that.
Where is he attacking her at all? He’s saying that the investigation should continue. That doesn’t mean he wants her arrested, or anything like that. It looks like he means that he wants the investigation to continue to conclusively clear her name.
Nobody, not even Sanders, is naive enough to think that would be Gowdy’s conclusion. Or, if it is, like the conclusions of the seven (?) investigations previous to it, that it would do anything but lead to another one, and more groundless assertions (like we see from adaher and Rubio) about how she was proven to be a liar.
She was proven to be a liar. She lied about why she had the account, she lied about classified info on the account, she lied about all her work emails being turned over.
Please, Clinton has many qualities that make her a better candidate than Bernie or Republicans. You don’t need to pretend she’s honest too. Argue the facts, not fantasies that don’t pass the laugh test.
See what I mean?
36-60 honest/dishonest. What the voters say is right, at least in the way that counts. It’s up to you to change the voters’ minds. All I have to do is sit back and cackle.
Refusing to accept the conservative version of what truth is doesn’t make Clinton a liar.
That is a far less principled interest in the facts than you accuse Clinton of having.
Like you did after the last presidential election?
Well doesn’t this make the story a bit more interesting:
Wonder what Bernie has to say about that? And Clapper is respected across the isle (except the far-left and far-right parts of the internet)
I would imagine Bernie would say it’s a good thing there’s an investigation so that facts could be established.
BTW, what isle is it that so widely respects Clapper? The Isle of Wight? The Isle of Capri? 
Your OP was, and is, pointless. About as pointless as your other attempt to smear Sanders with the “honeymoon in Russia” story, about which the facts are these:
In 1956, President Eisenhower launched the program that a decade later would be called Sister Cities International, a program still in existence today. The idea was to promote peace and understanding through connections between cities in the United States and, at first, Western Europe. The program soon spread. In 1973, Seattle became a sister city of Tashkent, the capital of Uzbekistan, then under Soviet rule. Other U.S.-Soviet sister cities soon followed despite the tensions of the Cold War.
In 1988, Burlington sistered with Yaroslavl, a city 160 miles north of Moscow. That was the same year Sanders married his second wife, Jane. In fact, the day after they married, they headed out to Yaroslavl. So, one could call it a honeymoon, and the pair have both done so, but jokingly or sarcastically. The reason for that is that they didn’t go alone. There were 10 other people from Burlington who went with them. It was a trip dotted with diplomacy, official meetings and numerous interviews. Not most people’s idea of a honeymoon getaway.
