Compare the populations....

Gallup has a poll looking at states with clear Dem party affiliation advantages (29 plus DC,) and the states with clear Repub party affiliation advantages (4).

Here's a look at the states and the top ten on each side.

Although, I wonder about this data. By their polling Texas is "competitive" (42 Dem/40 Repub)?

I'm thinking this extreme might be something of an artifact of the political environment with "independents" leaning Dem more prone to claim Dem affiliation while "independents" leaning Repub are more likely to deny their party.

Still interesting though.
