Judson Berger writes at FoxNews.com about one development that might cheer those who fear that Donald Trump has helped subdue Republican Party enthusiasm.

For all the attention on battleground polls giving Hillary Clinton the edge, Donald Trump enjoys at least one electoral advantage in his uphill climb to the White House: Republicans are outpacing Democrats in registering new voters in key states.

A review of registration figures shows that in the swing states that sign up voters by party, Republicans are seeing a significantly bigger boost since 2012. In states like Florida and Pennsylvania, the party has added tens of thousands of voters to the rolls at a time when Democrats have seen their base shrink.

“The numbers [in those states] … are a huge shift from what we’ve seen in 2012,” Republican National Committee spokeswoman Lindsay Walters said.

The surge doesn’t change the fact that Clinton leads, if only by a thin margin, in most battleground state polls, which presumably reflect the current voter make-up.

Fox News ratings show Clinton maintains the advantage in the Electoral College, while a Washington Post survey this week of registered voters in all 50 states reflects a similar dynamic. And in big swing states ranging from Florida to North Carolina to Pennsylvania, there are still more registered Democrats than Republicans.

But the registration shift since 2012 suggests Trump will enjoy a stronger base of GOP voters in some states than did Mitt Romney four years ago.
