The level of dishonesty required to beat Democrats at their own game in election fixing is much higher than most Reps would be willing to go.
Stronger laws to prevent rounding up old people, dead people, homeless people, and people in rehab to bribe them with votes are a great idea. But in many areas, we would be relying on Dems to both pass and enforce those laws.
I don't know the solution. We won't have honest elections with Dems in power, and we can't put Dems out of power without honest elections.
