Why Donald Trump Is Leading

Ron Brownstein: “The blue-col­lar wing of the Re­pub­lic­an primary elect­or­ate has con­sol­id­ated around one can­did­ate. The party’s white-col­lar wing re­mains frag­men­ted.”

“That dis­par­ity is crit­ic­al be­cause in both the 2008 and 2012 GOP nom­in­a­tion fights, voters with and without a four-year col­lege de­gree each cast al­most ex­actly half of the total primary votes… With the two wings evenly matched in size, Trump’s great­er suc­cess at con­sol­id­at­ing his “brack­et” ex­plains much of his ad­vant­age in the polls.”
