Roy Blunt Hits 50 Percent Mark in Missouri Senate Race

Seven-term Republican Rep. Roy Blunt has slightly increased his lead over Democrat Robin Carnahan, Missouri's Secretary of State in their race to win the seat of GOP Sen. Kit Bond who is retiring, according to a Rasmussen Reports poll conducted May 3.

Blunt has now reached the 50 percent mark while Carnahan's support is at 42 percent, with 4 percent preferring another candidate and 4 percent undecided. The margin of error is 4.5 points. In early March, Blunt led 47 percent to 41 percent.

Both get almost 90 percent support from members of their own parties, but Blunt leads among unaffiliated voters by 56 percent to 28 percent with the rest undecided or preferring someone else.
