I've heard the following arguments against all this:

• The CIA has lied before about the WMDs in Iraq. They can't be trusted. (Discrediting source)

• Of the IP addresses released, many were TOR exit nodes that are out of Russia's control. Those IPs can't be used as evidence.

• I, personally, haven't seen the evidence, so who knows what it says.

• Wikileaks has never lied about its releases, but the intelligence agencies have.

• Podesta said himself in the emails that it was a leak and not a hack. Obama also let it "slip" that it was a leak and not a hack.

• So what, the US meddles in elections. Therefore, we should all just shut up about this because we're being hypocrites.

Any others?

We need we'll-sources counter arguments to these. These are going to be the "climate denier" arguments of this issue.
