This will not be long as the title says it all. Definitely a pre-emptive point to make at this time. If Trump falls seriously ill in the coming days, the Biden-Harris campaign should absolutely continue. Nothing is to be gained politically by pausing the campaign if Trump is ill due to his own negligence and irresponsible behavior with regard to the coronavirus, it only highlights his unsuitability to lead the US. No GOP voters will be convinced to vote for Biden by pausing.
The entire election and the future of our system depends on massive turnout of Democratic voters, from the most reliable to the least reliable. The campaigning must continue.
