NASHVILLE -- A week after the release of a poll that suggests Republican U.S. Sen. Lamar Alexander would be vulnerable to a "credible conservative" in the GOP primary next year, the Alexander campaign says its own new poll shows the Tennessee lawmaker is in a "very strong position" to fend off GOP rivals.

The Alexander campaign's survey of 600 likely Republican primary voters, conducted Aug. 19-22, showed the senator's job approval at 69 percent with 24 percent disapproval.
