The degree of thumbing the scales has to outweigh unpopularity of the incumbent. High voter turnout will beat any attempts of deniable cheating. Which is why unpopular dictators end up imprisoning or disqualifying their opponents , and rather than subverting the voting process. America hasn't reached "desperate dictatorship" levels yet, nor will it be there in 4 years. Extrapolating from current events, congressional Republicans are barreling towards a midterm wipe-out.
