Yes, the democrats should challenge the election results because everyone knew Russia was going to try to hack the election. It seems like they may have done it in order to make Trump president. The race is too close to call in many states and Clinton won the popular vote.
Given the well-known quote from Stalin that "The people who cast the votes don't decide an election, the people who count the votes do", it's very surprising that this segment failed to address the key question of how a vote count can be verified when the mechanism of voting is electronic.
Democrats should not challenge the election results. Funny how these whiners only want to change results or the process when they lose. If they win under the same rules, then the process must be perfect, right? What a bunch of spoiled brat losers. Here's an idea. Try winning elections for a change.
It doesn't matter that Clinton won the popular vote. That is not what determines the presidency. Rather, there is no question that Trump won the electoral college. No amount of recounting will change that fact. The system we have is the system we should use, even if that gives results that some people don't like sometimes.
