Ljube: here are the racial crosstabs of the PPP poll that had Trump leading -
Clinton-TRUMP-Unsure
Base 43-45-13
White 38-50-12
Black 72-10-18
Other 52-40-8
I truly believe he has strong appeal in Bucks and Delaware which you can debate (at worst, stronger than Romney), and he will outperform significantly in Philadelphia. 13-15% of blacks is far from out of the question, and with the Street's campaigning for him, who knows? He just needs to make it the focus of his campaign, which I expect him to do since he accepted an invitation to speak here.
To be perfectly transparent - Christie got 14% of blacks and Carson got 12%, but that's all irrelevant now. Rubio got 10% vs. Sanders, and Trump got 20% against Sanders.
Romney got only 6% according to exit polls.
Smilo, thanks for this analysis!
Romney tanked with the working class too (not only the blacks). According to your analysis, TRUMP can improve on the Romney's numbers in the suburbs too. If he does that, he's won the election.
Clarko, do you have anything to add?
