Unions were motivated like never before, because the law affected ALL government unions around the country (indirectly). My bet is they ALL voted (add a few thousands out of staters and other fraudulent votes to that number), and the unions spent $35 MILLION - but still lost!!!
Imagine if it had been only state union money and votes. They'd have gotten creamed.
They couldn't pull this off nation wide, nor do they have the funds to do it state wide across the board (without another union funding stimulus package).
The majority of Americans aren't union thugs. The more the unions try to intimidate the America people, the more the American people will want them disassembled.
Let's put it this way - the union brown shirts are frightening people. No one wants to wear cement shoes or have their ribs busted for not voting correctly. No one wants another NAZI Germany.
The technique is to accuse those who oppose you of doing exactly what you are doing (voter intimidation, voter fraud, trampling on rights and liberties). They then reinterpret the Constitution to create rights that don't exist etc.. The socialist propaganda machine is in full throttle, and aimed squarely at the 2012 election cycle.
