Agree. Comey didn't want to be the guy who changed the course of history but, he loaded up Congress with enough info for them to try.

I don't think he loaded up Congress as much as he informed the American voter. The vote has far greater immediate repercussions than a trial and less public dissension. I agree that that he didn't want to be the Republican that charged Hillary during an election year. I think it all changed on the tarmac in Arizona when Bill and Lynch had their private meeting. Up until then, I think he was going to hand in his investigation as normal and let the DOJ decide. Of course Lynch wasn't going to charge and she was then going to bury the investigation. Comey did his job and she did hers, case closed and nothing can be done about it. After his tenure, Comey can tell everyone after how he felt and the evidence showed Hillary should have been charged, but it was Lynch's decision not to and he didn't say anything because it would not be appropriate for the head of he FBI to say such things.
However, that changed when Lynch and Bill were caught in a secret meeting red handed. There was no recourse. The only thing she and the DNC, could do, was to lay the decision at Comey's feet. I agree that he didn't want to be the Republican to bring her down. He probably got a lot of pressure on both sides through backdoor channels. Ultimately, his decision was going to be a historic one and would have tremendous impact on half of the population of the US. His remaining years at the FBI wouldn't matter and the FBI would carry that legacy forever. Now, he cannot put it on Lynch and he doesn't want the negative repercussions so what can he do? Punt to the voters, the biggest jury in the land. Give them the facts and let them decide in the upcoming election. Congress, as a secondary. However, with Congress there still has to be an investigation that would most likely run well into or end after the election (even worse for the US). They still have to go to the DOJ for prosecution, a DOJ that will still have Lynch as AG if Hillary wins. That will go no where. So, the voter is the best option to keep her from office. Then there is a much higher probability of getting an AG to prosecute her.
Also, the Clinton Foundation is still under investigation. I feel, as Doyle has said as well, that this is just the appetizer. The main dish could very well be public corruption charges for both her and Bill. If that is the case, you must keep her out of office and the best chance there again is the voter.
One thing that does bother me though, why were they so myopic on what they were investigating? I mean, the perjury and FOIA are low hanging fruit. Why didn't they grab them??
