Democratic leaders seem to have surmised that to keep together a party splitting both generationally and ideologically, they had to either court the radicals or risk early retirement.
Perhaps the most significant long-term development taking place in the Democratic Party is its surrender to the party’s Blame America First wing. One of many indications of this is House Democratic leadership’s ardent defense of its virulently anti-Israel, anti-Semitic, and fundamentally anti-American and anti-Western colleagues.
The Democrat establishment’s cave began when House Speaker Nancy Pelosi chastised Rep. Ilhan Omar for her anti-Semitic comments, only to then cravenly acquiesce to party progressives by passing a House resolution that refused to condemn Omar by name, and refused to solely condemn Omar’s offending anti-Semitic rhetoric. It accelerated with the party’s attack on critics of Omar’s comments seemingly trivializing the attacks of September 11, 2001.
Then, in the wake of Pelosi and House Majority Leader Steny Hoyer’s feckless, supportive responses for Rep. Rashida Tlaib following the firestorm she created with her historically illiterate, Hamas-ian hagiographyof Israel’s founding, the Holocaust, and the Arabs’ role in relation to both, the cave to the Blame America Firsters appears to be complete.
The Democrat Old Guard will no longer engage in even muted criticism of its Party’s provocative Young Turks. Rather, it will wholeheartedly defend the provocateurs and vociferously condemn their condemners
The pertinent question few are asking is, “Why?” Assuming the Democratic leadership is driven above all else by power, I suggest three primary reasons for this shameful shift.
