This is something I have noticed here in Florida. I also think Fox News is losing it's viewers for the same reason. 

Midterm elections are all about turning out base constituencies. Over the last few decades, there have been few more reliable voters for Republicans than white evangelical Protestants. This year, however, GOP candidates may be getting less help from this group—not because white evangelical Protestants are becoming less supportive or less motivated, but simply because they are declining as a proportion of the population, even in Southern states.

A look at generational differences demonstrates that this is only the beginnings of a major shift away from a robust white evangelical presence and influence in the country. While white evangelical Protestants constitute roughly three in 10 (29 percent) seniors (age 65 and older), they account for only one in 10 (10 percent) members of the Millennial generation (age 18-29). In the last few national elections, however, because of high levels of voter turnout, white evangelical Protestants have managed to maintain an outsized presence at the ballot box according to national exit polls, representing roughly one-quarter of voters.

But the fact that there are currently five Southern states—Arkansas, Georgia, Kentucky, Louisiana, and North Carolina— where polling shows that the Senate race margins are less than five percentage points indicates that 2014 may be the year that the underlying demographic trends finally exert enough force to make themselves felt.
