The GOP's biggest fear: voters.
Guy Cecil, head honcho at the Democratic Senatorial Campaign Committee (and rumored finalist for Hillary Clinton's campaign manager gig):
“Getting out the vote and protecting voter rights are critical to who controls the majority,” [Cecil] said, adding that the DSCC was especially concerned about North Carolina and Arkansas.
“There is a clear pattern in this country,” he added. “Where there are Democratic governors and Democratic legislatures, states are working very hard to think about how they can expand access to voting: vote by mail, online voting, early voting, Sunday voting.
“In places where there are Republican governors and legislatures there are moves to restrict access to the voting booth; require only a certain form of identification, limit the number of early vote locations, eliminate Sunday voting.”
If Republicans truly believed this was a center-right nation, and that they had the support of the populace, they'd be working hard to make sure
everyone voted. They'd be fighting hard for universal voter registration, and work to open up polls for longer periods of time, or even transition entirely to vote-by-mail.
But they don't believe any of that. They know they are a minority, and a shrinking one, and the only way to retain any modicum of power is to keep as many people from voting. Democratic base groups help them out by failing to turn out in mid-term elections, and it's a propensity they are more than happy to encourage.
Republicans have lost the American people. Every vote they work to suppress confirms that.
