I'll try to clarify my remarks, knowing full well that I may only muddle them further. The frivolous issue that the GOP is using is voter fraud. There is no evidence of any widespread voter fraud, but the GOP is using the perception to make it much more difficult to vote, putting in restrictions that are aimed at young voters, the poor, and minorities.
They're also making up various issues to undermine the right to choose. From state to state, these folks who are supposedly against regulations are putting in regs about office space, bathrooms, etc, that are specifically designed to shut down or impede access to a legal medical procedure.
The issues of voting rights and abortion are indeed important issues. However, the GOP is using frivolous issues to circumvent taking these issues on directly.
