Here's another interesting comment from Sen. Rand Paul (R-Ky.) during his sitdown with former senior Obama adviser David Axelrod on Tuesday: Paul said that the Republican Party might be over-selling incidences of voter fraud.

The GOP has cited actual fraud and the potential for fraud while pushing new voting laws, including requiring voters to present identification at the polls. Such laws have passed in numerous GOP-controlled states in recent years, but Democrats say the efforts are aimed at reducing the vote of groups less likely to carry IDs -- most notably minorities -- who favor Democrats.

From the transcript:

PAUL: Dead people do still vote in some elections. There still is some fraud. And so we should stop that, and one way of doing it is (driver's licenses). AXELROD: Although the incidence of fraud is relatively small. PAUL: It probably is, and I think Republicans may have over-emphasized this. I don't know.

Paul did say that he supports voter ID efforts as a minimal standard and noted that you have to present an ID to enter government offices.

But he had a different view of calls by Republicans in some states to curtail early voting, which tends to favor Democrats more than Republicans.

"I don't think early voting is biased one way or the other," Paul said. "So I think eliminating it is a mistake for the -- Republicans who want to make their whole thing eliminating early voting, I think that's a mistake."
