In Missouri - McCaskill and Talent deadlocked

After all their ads, attacks and debates, Missouri's two major candidates for the U.S. Senate are heading into the campaign homestretch in roughly the same spot as they were almost a year ago — deadlocked.

U.S. Sen. Jim Talent, a Republican, and his Democratic rival, state Auditor Claire McCaskill, also are finding their battle increasingly entwined with the fight over Amendment 2, the ballot proposal to protect all forms of stem cell research allowed under federal law.
