In 1968, Nixon got 43.4% of the popular vote compared to Romney’s 47.2%, so I doubt Nixon got a higher percentage of the white youth vote than Romney.
In the 1972 election, we had no combat troops in Vietnam, and the Draft ended 3 months later.
When I say we have a “race” problem, I mean we have a LEGAL immigration problem.
Since the Reagan Amnesty in 1986, we have naturalized 20 million new Socialist voters.
In 1972 we still had the draft and were still in Vietnam, and I was in the army and the democrats got 46% of the youth vote and Nixon got 52%, and in 1968 53% of the youth voted against the democrats since George Wallace was running and won almost 14% of the vote, and was seen as to the right of Nixon, with Veep candidate Curtis LeMay.
Yes legal immigration is the main problem, but not the only one, the white under 30 vote is far more liberal than it used to be.
Remember that Romney was too far left to have run for either party in the 60s or 70s, too far left to get out his base, and you are comparing pure white under 30s with the total under 30 voting of the past, yet the radical left, and dismal failure Obama still did great with the white under 30s in 2012.
You seem determined to make immigration the sole problem for some reason, and seem to be agreeing with the writer’s mistaken history of the under 30 vote.
