How is this possible?

One question: How are caucuses legal in a democracy?

I know that there are TONS of violations of the Voting Rights Act and I don't want to get into the 2000 and 2004 elections, but I cannot believe this is allowed to happen.

The issue is obviously intimidation. I couldn't even wear a Kerry-Edwards shirt within 100 yards of a voting center, but caucuses allow blatant and possibly forceful voter coercion.

So, fill me in. How can this be?
