Sure, so Hillary can beat him by an 80/20 margin.
Fewer pledge allegiance to the GOP
The survey, by the nonpartisan Pew Research Center for the People & the Press, found a "dramatic shift" in political party identification since 2002, when Republicans and Democrats were at rough parity. Now, 50% of those surveyed identified with or leaned toward Democrats, whereas 35% aligned with Republicans.
What's more, the survey found, public attitudes are drifting toward Democrats' values: Support for government aid to the disadvantaged has grown since the mid-1990s, skepticism about the use of military force has increased and support for traditional family values has decreased.
I find it hard to believe opinions can shift that dramatically.
