Traditionally, conservatives are seen as distrustful of the government, as wanting less government, more personal autonomy. Yes? And liberals, well, the opposite.
In Indiana, similar to many other states, a law has been passed requiring a photo idea to vote. It has been controversial and is about to receive a ruling from the US Supreme Court.
Reflexively, liberals have lined up in opposition and conservatives in support of this law, and others like it. Why? The parties are shifting? It's the same thing with surveillance, no? Shouldn't it be the Republicans who are fighting tooth and nail (ahem, not to suggest that the Democrats are doing that) to keep (big) government from becoming big brother?
Or maybe it has nothing to do with principles, and it is political. IF a political party is to benefit from the VOTER ID Act, it is the Republicans, because those who are most likely to not vote are often Democrats. So, you have Democrats fighting tooth and nail all the way to the Supreme Court over it. On the other hand, increased surveillance is part and parcel of the patriotic and Republican defense of our country - national security national security national security - which was a source of political strength for the Republicans and prompted a scattered knee-jerk reaction from Democrats. Perhaps?
