(CNN) - We had a nice surprise in The Situation Room on Tuesday when two special guests dropped by.
I’m talking about Edith Pfeffer and Carolyn Tallett.
They are the famous “Edith and Carolyn” of Clinton County, Iowa. As you might remember, they helped us at CNN resolve the mystery of the outcome of the Republican presidential caucuses in Iowa in the wee hours of the night back in January.
They are both lovely ladies, deeply committed to making the political process work. I told them that I deeply admire their dedication and hard work.
Their visit reminded me of the many thousands of Americans who give up their free time to volunteer to guarantee that the political process works smoothly across the country. They are the ones who make sure that our elections are free and fair.
We see them at the polling places, where they await the arrival of voters and register them. Later we see them counting ballots and dealing with potential disputes. They are the backbone of the democratic political process in the United States.
So as the voting continues across the United States – including Tuesday in Illinois – let’s take a moment to thank these volunteers, whether they’re Democrats or Republicans, liberals or conservatives. Just a thought.
