Yes, the US should sanction anyone who tries to interfere with our elections. What’s really more important is that the US must make our elections less vulnerable by securing the ballot box, by using trustworthy bipartisan or non partisan vote counting. The US must immediately begin the hard trip back to real public education so that the people are less vulnerable to propaganda. DeVos and others who demolish American public education are just as culpable as foreigners who interfere with our political process. Intentionally educating some students less thoroughly is part of a conservative political process to make ignorant voters who are easily led.
