President Barack Obama took 71 percent of the Hispanic vote in 2012, up from 67 percent in 2008. African-Americans vote overwhelmingly for Democrats (Obama got 93 percent of the African-American vote in 2012, and John Kerry won 88 percent of that vote in 2004). Asians, who were the fastest-growing ethnic group between 2000-2010, have tended Democratic this century, with 73 percent voting for Obama in 2012.
Players other than offensive linemen may enhance the success of a zone blocking scheme. For example, in a run-based spread attack like West Virginia's the primary responsibility of receivers is less to catch passes than to execute downfield blocks, springing the ball carrier and extending the run.n a zone blocking scheme, fleet-footedness and athletic ability trump size as desirable qualities in offensive linemen.
Just to distill it a bit: X-technique refers to where a defensive lineman lines up relative to the offensive line. A 0-technique lines up directly opposite of the ball-snapper (center), and the 9-technique lines up outside the tight end, who is usually the widest player on the offensive line. This picture, from John's link, is fantastic.
