Republicans are not the ones pushing the idea that everyone secretly vote by mail. We should limit absentee voting to justified instances, such as soldiers in the field or people in wheelchairs. However, the individual should not send his ballot in. A government approved ballot collector, accustomed by representatives of any party willing to send people in the role of vote observers transparently videotape the entire process.
By that logic, we should have in person tax collection... and if you don't show up, you don't have to pay your taxes.
Oh, no, wait. We allow tax filings by mail. We allow tax filings over the internet.
Same with paying utility bills, renewing driver licenses, collecting census information, etc.
The only reason why you guys want lower voter turnout is that lower voter turnout benefits Republicans.
