GOP, of course, stands for the Grand Old Party...a collective noun which should, in fact, be treated as a "third person singular noun."  However, playing grammar pedant and belittling a writer's treating it as "third person plural" instead of addressing the substance of the post doesn't speak well for Motley. 

 Clearly the Republicans realize that high voter turnout benefits Democratic candidates and, therefore, pass laws and develop voting policies and systems which suppress voting by minorities, the urban poor, the elderly, and "new" voters who, overwhelmingly, support Democratic candidates.  The GOP policy and practice is extremely simple:  If you can't convince people to vote for your candidates, develop procedures to keep them from voting at all.  It's a nasty, cynical tactic, but it's been all too successful.  

As the RG editorial notes, "vote by mail" eliminates all possibility of polling place voter fraud and would, more importantly, eliminate GOP voter suppression Gary Crum
