Do Republicans fear democracy?
Of course they do.
They have chosen a narrow base, compared to what the leaders of their party wanted in 2014. Gone is the appeal toward minorities, and in is the fear of the "other".
Their base of rural older whites is becoming a smaller and smaller percentage of the voters, so they need to bring out a higher and higher percentage of their base, while reducing the Democratic percentage coming out to vote.
As we see, states have moved over the past few election cycles. VA, NM and NV are now blue states. AZ is purple and moving to blue. The battlegrounds over the next couple cycles are TX, NC and GA. For 2022 and 2024, the strategy is to have the Republican legislators reduce the number of Democratic voters, and to control the voting and certification process.
It is critical for them to regain AZ and GA. Then, they will be back to the 2016 strategy of needing to win MI, WI and PA.

TO BE CLEAR
Large turnouts of all voters in 2022 would be a total disaster for Republicans.
