Missouri U.S. Senate candidate John Brunner is the slight favorite going into Tuesday’s Republican primary, according to a poll released Sunday night.
A poll by Democratic-leaning Public Policy Polling shows the St. Louis businessman with support from 35 percent of likely voters, followed by Rep. Todd Akin at 30 percent and former state treasurer Sarah Steelman at 25 percent. The candidates are vying to unseat Democratic Sen. Claire McCaskill.
While the poll shows all three Republicans have a chance to win on Tuesday, its results are slightly different from other polls that have shown Mr. Akin as running third in the race.
All three Republicans have ramped up their campaigning in recent days and some national figures have entered the fray, including former Alaska Gov. Sarah Palin who has endorsed Ms. Steelman and Oklahoma Sen. Tom Coburn who is backing Mr. Brunner.
A poll released last week by Rasmussen Reports showed that all three candidates would be favored over Ms. McCaskill in a general election, with Mr. Brunner and Ms. Steelman holding six-point leads over the Democrat in a hypothetical election and Mr. Akin having a three-point lead.
