The first signs of change appeared in the 2012 election, as the young people voted for marijuana legalization (and gay marriage) in two states and the hundreds of millions spent by the wealthy on campaign ads (enabled by the Citizens United ruling) failed to produce material results. Unfortunately, it appears that the older generations' viewpoints are largely stagnant, so this change will probably have to occur one funeral at a time.
