Personaly I dont believe this poll. If you look at the sampling it just says
“In the latest Pew Research/National Journal Congressional Connection Poll, sponsored by SHRM, conducted July 22-25 among 1,004 adults, 46% say that following the policies of Obama administration would do more to help the economy improve in the next few years, while 29% say that following the Bush administrations policies would do more to help. Nearly one-in-five (17%) volunteer that neither administrations policies would help.
The adult voters who are they likely voters,registered voters,felons who knows. I just think the numbrs are all over the place and possible oversampling in one area or another IMO
Pew had another bogus poll some years ago showing campaign finance reform as one of the top two issues. Their liars and should be ignored.
