Austin's NBC News affiliate has conducted a pre-debate poll of the electorate and this is what they've found :

The race for the Democratic nomination is too close to call. The large percentage of "undecided" voters give even more weight to the CNN debates Thursday evening. As Senators Clinton and Obama both tour Texas, they will be reaching out to the undecideds to close the gap.

If the election were held today, who would you vote for? Democrats:

• Clinton 46%
• Obama 45%
• Undecided 9%

Margin of error: +/- 4%

If the election were held today, who would you vote for? Republicans:

• Huckabee 30%
• McCain 52%
• Paul 9%
• Undecided 9%

Margin of error: +/- 4%

Voter interest is high for the March 4 primary and as Texas plays a role in deciding the nominee, the expected voter turnout is historic.

They are going to conduct the poll again after the debate. What's really interesting is the reason why they chose the company conducting the poll, Constituents Dynamics:

Our second poll will be conducted after Thursday's debate with results airing next week. Both polls are being conducted by Constituent Dynamics, a Seattle-based company which uses an automated polling method. We chose the company, because the automated method increases sample size (1,340 registered voters) and includes calls to voters on their cell phones.

I'm really curious if they keep demographic information during these polls beyond the age range. I'm particularly interested to know the ethnic and racial composition of the first age bracket, the 18-39s. I'd love to know if the majority is minority, which is the trend of millennials.
