For those who once had hope that millennials were less susceptible to hyper-partisanship, the latest survey from the Harvard institute of Politics comes as another blow.  In October 2010 Obama's approval rating was 79% among Democrats, 18% among Republicans.  A year later it was 87% and 12% respectively. It now stands at 86% and 10%. 

Thus it's no surprise that on policy matters the survey reports a "significant hardening of views":

From immigration to government spending to views on morality, the divide between political parties, even among our youngest voters, is stark. For example, in the Spring of 2010 Democrats were three points more likely than Republicans to agree that recent immigration into the U.S. “has done more good than harm” — and today they are nine points more likely. In 2010, Republicans were 13 points more likely to disagree with that statement, today they are 27 points more likely to disagree.
