I believe I have answered this a few times, including a Hub, but here goes...
#1 - The 47% statement is not that far off. Though its probably more like 30% or a bit more. 3rd and 4th generation Welfare recipients, 109 million Americans total on some form of 'Welfare'.
#2 - Obama got that 30% out to vote in the key swing states like Ohio. They literally dragged people out of bed, drove them to the voting booth, and told them how to vote (any stories you hear about free phones and free meals were probably true as well).
#3 - The Unions were paid off for support in advance, in the form of the stimulus package, which was a major kick-back to Unions and other Obama supporters.
#4 - The Obama Campaign really hit a home run painting Romney as ANTI-Woman and a legitimate threat to Abortion. ... even though we've had Abortion in America for over 30 years (legal in every state) even though it wasn't even an issue Romney cared to address, and would likely have no opportunity to.
#5 - One can not over-estimate the importance of #4. Women make up 53% of the voting block, and about 60% of them voted against Romney (almost 80% of single women)... you CAN'T win the Presidency with less than 50% of the woman vote.
So long as Republicans allow themselves to be painted as ANTI-Women's Rights and ANTI-Abortion and allow people to run for office that say idiotic things like "pregnancy from Rape is still a miracle" ... they will lose.
The America our founding fathers envisioned died years ago...
The policy of the American government is to leave their citizens free, neither restraining nor aiding them in their pursuits.
To take from one because it is thought that his own industry and that of his father’s has acquired too much, in order to spare to others, who, or whose fathers, have not exercised equal industry and skill, is to violate arbitrarily the first principle of association—the guarantee to every one of a free exercise of his industry and the fruits acquired by it.
The majority, oppressing an individual, is guilty of a crime, abuses its strength, and by acting on the law of the strongest breaks up the foundations of society.
I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them.
~ Thomas Jefferson
There was a time, when only those who owned land could vote, now those that depend on government entitlements for survival have become the biggest voting block (non gender).
