If anything, the Democrats have been co-opting much of what used to be conservative values that Republicans used to exploit. The map suggests that many of the demographic groups that would have voted for Eisenhower in the 1950s have gone to Barack Obama, or that the states have specific cultures favorable to Obama were generally favorable to Ike in the 1950s. It is amazing, is it not, that Eisenhower won some states that have consistently been tough wins for Democrats beginning in 1928 -- Massachusetts and Minnesota, the hold-out states preventing 50-state landslides for Nixon in 1972 and Reagan in 1984, and Rhode Island, one of only two states outside the South that went for Al Smith in 1928 (the other such state was Massachusetts).
I'm unsure of what you mean when you say 'values' and then mention traditionally Republican demographics. Democrats have undoubtedly moved much further left since the Third Way days, and we are not really like the old Eisenhower-era Republicans, either. It's more like both the party and the electorate has changed. Well-educated Millennials will continue to cannibalize the white college-educated demographic, and Millennials are the most liberal generation in a long, long time. In addition, the GOP itself plays a role in chasing away certain states/demographics.
I think he is talking about patriotism, national defense, unity etc.
