I wouldn't worry too much. If 50% is the best he can do in STL, he's toast. They've been calling him One Term Bob on the hill for the last 2 years.
Good observation. Those unfamiliar with Missouri may think Governor "Holdup" will get re-elected. But as you say, if that is the best he can do in St.L? He's toast come November! Hard to believe he is an Ozarks boy. I am sick of his gun-grabbing, anti-RKBA rants. His obstruction of CCW. His pro-tax, liberal agenda, as well as his union pandering.
I hope to hell SW MO can likewise rid itself of his flaming liberal brother! A judge up in Greene County (Springfield) who has a thing for releasing dangerous thugs on low bail amount$!
