We have absolutely aborted the campaigns of incumbent presidents before. The DNC and White House however worked very hard to shut down any criticism during the primary timeframe, refused to have debates, disburse money, etc
So if they're going to treat this full election as a preference poll on Biden, then so will the people. And his approval numbers are bad.
How bad do you want to roll those odds on trump getting elected again?
Also, who are you supporting for president this time round, and what do you figure their chances are of winning?
Are you talking about Truman? One guy who started to seek the presidency, after serving 1.5 terms, and then pulling out before being the presumptive nominee? I don't think history is on your side for this one.
Also, answer the questions please.
Edit: You actually said "We have absolutely aborted the campaigns of incumbent presidents before." Implying that the candidate did not win their nomination. Let's go ahead and put those goalposts back where they were initially.
Clearly you don't understand what a whataboutism is.
Your position was logically indefensible, which I have demonstrated (without your answers, or lack thereof, to my original challenge) even after you moved the goalposts. If you wish to discuss this further, you'll need to clear the initial (very low) bar I laid out for honest discourse. It's time you put some skin in the game, instead of polluting my screen with vacuous replies from the safety of political/social anonymity.
The idea that campaigns get aborted is indefensible? That we don't elect presidents for 8 years? or That the DNC leans hard on any dissent to prevent such an end to Biden's campaign? Which idea there is indefensible? The only thing you've done is denied, fearmongered, and shouted what about trump. That's not something I'm going to spend more than a couple minutes responding to.
