By that standard, we'll never have unity and civility because if the Republicans are in power, Democrats don't think they should be civil or cooperative. So, when Democrats are in power, Republicans won't think they should be civil or cooperate.
Not so. No party has EVER behaved this badly after losing an election as the Democrats are doing now, and never has a party been caught so red-handed cheating so much....
One of the Differences between the GOP and DNC is in how they approach trying to win and how they handle defeat.
The GOP tries to win - Democrats attempt to win at any cost.
Rigging primaries, cheating in debates, breaking election laws, paying thugs to beat and bloody opposition supporters, collude with / pay foreign spies and Russians for their help / Russian-authored dossiers they then illegally use, etc...
If the GOP loses they try to follow Obama's advice - Win some elections" If the Democrats lose they start up witch hunts, declare anti-American 100% commitment to seeing the govt & President fail, call for women and even the President's son to be kidnapped / raped, etc...the 1st Lady / their candidate publicly calls for more violence / intolerant violence....
