In a sign that the Senate Republicans could be in danger in even states usually deemed safe for them, a new Rasmussen poll of Texas finds that Sen. John Cornyn (R) could very well have a race on his hands against Democrat Rick Noriega, a state Representative and Iraq War veteran:

Cornyn (R) 47%
Noriega (D) 43%

Sample size: 500 likely voters.
Margin of error: ±4%

Noriega will have his work cut out for him, though -- the latest FEC reports show Noriega with only about $300,000 cash on hand, compared to the incumbent's $8.6 million cash on hand.
