along with his idiotic rationale, ignores a small detail.
They gave some of that information to the trump campaign. They stole data from a US political party's server and gave that data to their opponent. Additionally they used that data to pinpoint target propaganda campaigns via social media.
Let that sink in.
Don't believe me?
"Trump also changed his weekend schedule on the fly, announcing to supporters in Tampa that he would be making a stop in Democratic-leaning Minnesota. The campaign also said Trump will visit Virginia and Michigan on Sunday. Meanwhile, the campaign canceled a planned appearance in Wisconsin, which also tilts Democratic."

Why did he waste time in places he shouldn't have won in the weekend preceding the election? What information gave the campaign the insight to do so? It certainly wasn't poll data.
I've never used the phrase "illegitimate president" because he was actually elected by Americans. I am however convinced his campaign knowingly cheated and colluded with russians during the campaign.
