Historically in the United States (at least for the last 50 years), the Republican political party has taken the most actions to restrict access to voting, unfairly redistrict to give them an advantage (gerrymandering), or simply screw with the voting system (to their advantage). Fringe local Democrats sometimes play with gerrymandering[0], but not nearly at the same rate. [1][2][3][4]

Given that the current party with federal power is the Republican party, I would argue there is no better time for them to pass as many vote-restriction laws as possible. Vote restrictions typically target the poor and minorities, who typically are Democrat party voters. The wikipedia article I linked is actually a remarkably good overview of the recent history of this issue in the USA.

It doesn't matter. Any of them.
