If you knew all this then why did you pretend you didn't? Why do you assume I'm a Democrat? I'm an American. I am upset by any foreign attack on my country. Why aren't you? 
Do you believe Putin more than our own Intel agencies? Trump does. Are you ok with unrelenting derogatory attacks on the women and men who put their lives on the line defending our country? Trump has attacked them incessantly and has yet to say a single negative thing about Putin. In fact he apologizes and praises him constantly. Do agree with that? 
Trump (and Putin) and many reasonable and intelligent people (apparently including you) want to turn this attack by Putin on our country into a partisan issue. It isn't. 

Our nation and our allies are under attack and we are about to put a President, Cabinet and Party in power who either fully support the Putin/Trump axis or lack the integrity to speak up against them. 
What true patriot can stand by silent and watch this happen? Can you?
