A new statewide poll gives Governor Bob Holden a six-point lead over challenger Claire McCaskill in the Democrat primary for Governor. A survey run for the St. Louis Post-Dispatch and television station KMOV shows Holden up 46-40 percent, with 14 percent undecided. One of the pollsters says undecided usually break against the incumbent. The survey also shows voters’ unfavorable reaction toward Holden is about 40 percent higher than it is toward McCaskill. The poll says 45 percent of those surveyed have an unfavorable view of Holden. It’s only 29 percent for McCaskill. The poll finds that if the general election were today, Matt Blunt would be favored over Holden 45 to 44 percent, but McCaskill would beat Blunt 44 to 42 percent. Both figures are well within the margin of error in the poll.
