Little has changed this month in Missouri’s race for U.S. Senate, but Republican Congressman Roy Blunt now earns 50% support for the first time against Democrat Robin Carnahan.

The latest Rasmussen Reports telephone survey of the state’s Likely Voters shows Carnahan, Missouri’s secretary of state, with 42% of the vote. Only four percent (4%) would opt for some other candidate, while another four percent (4%) are undecided at this point.

Still, support for both candidates has changed little over the past several months. Since January, Blunt has earned between 47% and 50% support. His support was slightly lower in September and December of last year.
