Why send a man, of sorts, to do a job that a woman could do better, under this regime? Obama has been getting down and dirty on President Trump. Yes,  this is from the man who continues to have a shadow over the legitimacy of his presidency, via his allegedly fake birth certificate, not as if anyone care anymore, with there being bigger fish to fry:

     For Obama, with all progressives, there is some existential wrong about Trump being president, and no doubt about “deplorables” voting for him, or even existing:

As Pat Buchanan points out, this is all about regime change, as the elites of the Deep State move to correct the error of allowing “we the people” to save a say in their rule:

“For what is afoot here is something America specializes in — regime change. Only the regime our establishment and media mean to change is the government of the United States. What is afoot is the overthrow of America’s democratically elected head of state. The methodology is familiar. After a years-long assault on the White House and president by a special prosecutor’s office, the House takes up impeachment, while a collaborationist press plays its traditional supporting role. Presidents are wounded, disabled or overthrown, and Pulitzers all around. No one suggests Richard Nixon was without sin in trying to cover up the Watergate break-in. But no one should delude himself into believing that the overthrow of that president, not two years after he won the greatest landslide in U.S. history, was not an act of vengeance by a hate-filled city that ran a sword through Nixon for offenses it had covered up or brushed under the rug in the Roosevelt, Kennedy and Johnson years. So, where are we headed?

If November’s elections produce, as many predict, a Democratic House, there will be more investigations of President Trump than any man charged with running the U.S. government may be able to manage. There is the Mueller investigation into “Russiagate” that began before Trump was inaugurated. There is the investigation of his business and private life before he became president in the Southern District of New York. There is the investigation into the Trump Foundation by New York State. There will be investigations by House committees into alleged violations of the Emoluments Clause. And ever present will be platoons of journalists ready to report the leaks from all of these investigations. Then, if media coverage can drive Trump’s polls low enough, will come the impeachment investigation and the regurgitation of all that went before. If Trump has the stamina to hold on, and the Senate remains Republican, he may survive, even as Democrats divide between a rising militant socialist left and the Democrats’ septuagenarian caucus led by Hillary Clinton, Joe Biden, John Kerry, Bernie Sanders and Nancy Pelosi. 2019 looks to be the year of bellum omnium contra omnes, the war of all against all. Entertaining, for sure, but how many more of these coups d’etat can the Republic sustain before a new generation says enough of all this?”

     That is the problem: the “good men” have sat on their hands and put up with the triumph of evil for so long, that few of them remain, and a point of systems corruption of such a high level of corruption and tyranny has been reached, that it is now difficult to chart any program of reform. It is best that this is said now, because other countries need to start preapring for what is to come. Perhaps when buildings get too dilapidated, by the actions of the white ants, there is no alternative but to tear them down and rebuild. Or else, they simply collapse on everybody with no chance to escape.
