…it seems much more sensible to me that the FSB would scan the e-mails for really damaging stuff, show some of what they have to Podesta or Hillary’s people directly (or leave it implied by omission), and then release the rest to Assange, with just enough moderately juicy stuff left in to make it seem moderately interesting. This would give Russia some credible leverage over a Hillary presidency, since they would have already shown their willingness to interfere in American politics, while holding back the goods.
Releasing everything in an attempt to get Trump elected seems odd, especially given that it would have a high chance of failure from the beginning and wouldn’t give them meaningful leverage over him once in office, if it succeeded. It’s not like the FSB doesn’t have enough manpower to scan through all the emails the way Trump supporters now are doing.
On the other hand, if you take this point of view, you have to assume that ramping up US-Russia tensions is in the interest of both Putin and Hillary. Which doesn’t seem all that hard to believe, really.
