Missouri seems to be a tie

St. Louis Post-Dispatch and KMOV-TV hired Research 2000 to conduct a poll of the presidential preferences of Missourians. The results show a statistical tie:

McCain 47
Obama 46

The poll has a standard error of +/-3.5. AP observed:

The poll shows the race between McCain and Obama is roughly even in Missouri, a change from just last week when McCain held a 4 percentage point lead.

The poll's internals suggested more respondents trusted Obama than trusted McCain to manage the economy.
