People have circular logic...or lack thereof.  I'm not defending Trump in any way.  He's a complete caricature that will cause headaches for Democracy for years to come.  He'll probably finish off Liberal Democracy a mortal blow.

Trudeau's boss, Chretien, has business dealings with Putin and has praised him in the past.  Then Putin got Trump elected.  Now the Liberals in Canada recoil in shock when they see Trump being a buffoon.

Maybe if they didn't support Putin in the first place, Putin wouldn't have been able to get Trump elected.

Same with Obama in the US.  The Democrats were weak on Putin.  Both Obama and Hillary could have skipped the "reset."  US Intel agencies warned Obama back in 2014 that Putin would try to interfere, but Obama refused to listen.

Now Putin's man in D.C. , Trump, is acting like a piece of malware.

The Left's actions fuel the Right...and the Right's actions fuel the Left.  It's all one pendulum moving back and forth.  Both sides cause their own demise.
