Well then try for a minute to put yourself in the shoes of the Obama voters. In 2008 Obama got 10 million more votes than McCain. Perhaps they thought the President and the Senate should work together to fix the problems of a troubled nation. To some of those voters it sounds like "my number one duty is to thwart the will of the people."
If that is what they thought, that expectation is unreasonable and reveals an ignorance of our system of government. We are not a parliamentary democracy where if you win the election, you are in complete control. If they thought "we now get everything we want because our guy won the Presidency", they're wrong. And the reason they couldn't get everything they wanted -- single-payer being the biggest item -- was because a bipartisan majority in the House didn't want it.
I'm not willing to walk a mile in the shoes of emotional children throwing a temper tantrum.
McConnell was stupid to say what he said publicly, but he said nothing that both sides don't think the second an election is over. And there is absolutely nothing wrong with promising to oppose the agenda of a President you don't like. Zero. Saying that you want to ensure that a President only serves one term is qualitatively from what the Dems did with Trump, which was trying to prevent him from serving the single term to which he was already elected. When an election ends with a result we don't like, the proper recourse in a republican form of government is to try to win the next election. It is
not to attempt to undo the results of that election.
But most importantly, there is a massive, qualitative difference between elected legislators voting against an agenda they oppose -- which is what Republican dids -- and Democrats calling for
incivility against Republicans in general. That is
monstrous. And just as an aside, it is wrong to equate "respect" with "civility". It is entirely possible to have no respect for someone, but still treat them civilly. In fact, it is essential that is how we behave in a democratic form of government. It's what distinguishes us from a third world thugocracy where the future is determined by who can get the most goons in the street.
