1. Republican women:

In this month’s Public Policy Polling survey of national GOP primary voters, Paul win 22% of men (tied for first place) but only 12% of women (fifth place).

The story was the same in last month’s Quinnipiac University poll of national GOP primary voters. Paul nabbed 18% of men (2nd place) but only 11% of women.

In limited state polling, we’re seeing the same thing. For example, in PPP’s poll of Pennsylvania, Paul won, once again, 22% of men, but only 11% of women.

In PPP’s survey of Wisconsin, he took 12% of men and only 5% of women.

2. Young black voters:

Sen. Rand Paul’s speech at Howard University this week — the first appearance by a Republican politician at the historically black college in over a decade — will focus on civil liberties issues, but it represents a far bigger test: can a conservative Republican reach a predominantly young, predominantly black audience?
