Unfortunately, abstaining from the process won't change anything. There's Say's Law to deal with. Also, remember who controls the reportage of the election returns. They can make the final tallies look like any percent of the electorate turned out they think is credible.
There are a few alternatives worth trying:
1) Agitate for a strong version of a "None of the Above is Acceptable" choice on every ballot: One in which if NOTA "wins," the office goes unoccupied and its powers go unexercised until the next general election (probably requires a state constitutional amendment, but that's a lot easier than amending CONUS);
2) Mass takeover of local GOP chapters, that more freedom-minded persons become the candidates available to us to vote for;
3) Absolute refusal to donate to the campaigns of unsatisfactory candidates or to "general" campaign-funding institutions such as "national" Republican Congressional or Senatorial campaign committees.
Down here in NY's 1st Congressional District, we have a choice between a nebbishy Republican and an openly corrupt Democrat. The turnout for that election might not reach 20%...but one or the other of them (probably the Democrat) will occupy the seat anyway. Only taking over the local GOP chapter could have produced a better candidate. The question that would leave us is whether such a candidate can win in NY Metro or its suburbs. But it's a question that deserves to be answered.
