It is easier than ever before to register to vote, and especially to vote in the US. The term "voter suppression" was made up to defame legal activities such as voter ID laws and suggest that they are illegal. The Democratic administration's concerns regarding voter suppression are manufactured by them, and amplified by the press. Such concerns are invented to criticise the integrity of American presidential elections.
Sore losers may use the term voter suppression to detract from their own loss and suggest that it could only have been caused by conspiracy.
