Republicans Now Outnumber Democrats

This month, for the first time since Rasmussen Reports has been measuring partisan affiliation, more American adults describe themselves as Republicans than Democrats:

These numbers are based on a survey of 15,000 adults, an unusually large number by polling standards. If affiliation were measured among likely voters, the numbers would be even more favorable to the GOP.
The political tide is still flowing strongly in the Republicans’ favor. It is hard to say, at this point, how far the tide might carry Republican candidates and principles.
