The Democrats are voting in these primaries and they are voting for Romney. Forget that propaganda about voting for Santorum. I am a registered Democrat of 30 years standing. I maintain that registration partly because it gives me access to what local Democrats think. A lot of them have reregistered as Republicans this year to vote for Romney just as they did in 2008 to vote for McCain. In 08 they knew that the kenyan was the nominee long before the MSM or the Republicans figured that out. This year there is no motivation to vote in their own primaries because the kenyan is already the nominee. Romney is the ideal Republican candidate for Democrats. Because he cannot believably distinguish his policies from those of the incumbent he has little chance to win the election and if he does win it there is no loss to the Democrat vision of America, just a hiatus while their policies are still being implemented, probably faster than they could do it, and he will lose the republican House in 2 years and the Democrats, perhaps the kenyan, will easily regain the presidency in 2016.
There is a concerted effort by the Democrats to disrupt the GOP primary this year and Michigan is where they would be able to make that happen.
And think again who they voted for........Santorum, NOT Romney. It's a simple proven fact. Even more disturbing is, every one of these Democrats are planning on voting for Obama in the General and believe that Santorum would be the easiest of all the candidates for Obama to win against.
