Because we're not a banana Republic. This is America. One of the great things about it is the peaceful transition to the next POTUS, and that is by the LOSER conceding.
Questioning an Election that is conducted on Diebold Voting Machines, a company that it has been demonstrated in the past is "In Pocket" of the Political Elite and TPTB is NOT the same as Bloodshed in the streets which is the comparison your example of how detestable not conceding would be, relies upon.
So that whole "OMG UnAmerican & Dangerous" line of argument you and other Lefties use is totally invaild.
And you all fully realize this yet you keep right on beating that Not Applicable/Invalid Comparison Drum.
Only Valid Fear of a candidate questioning an election exists on the part of those who have rigged elections and will, if necessary, rig this one. Bcuz they fear eyeballs looking into them, too deeply.
Who was it that got ZERO Votes in Philadelphia? In some Prez Election?
McCain?
I forget. Someone did, though. Zero Votes.
There has been, and will be, obvious Election Rigging. Like all else though...Americans will be apathetic about this. Bcuz "Stupidest Generation" is so well within their grasp they can taste the seizng of that title. You should trust that they, we, will get that.
