In terms of illegally obtained content, the Democrats had no problem claiming higher ethical ground in releasing a tapped cell phone conversation of Newt Gingrich http://www.daviddfriedman.com/CCP_97/Gingrich%252fMartin%252...

And if you want to focus on foreign (illegal) involvement in U.S. elections, look no further than the alleged Chinese involvement in the 1996 presidential election https://en.wikipedia.org/wiki/1996_United_States_campaign_fi...

My point being, this is almost entirely political. It changes no ones mind.
