One of the dangers of a contested primary is that it will force candidates to try to out-do one another in appealing to their party's most hard core elements, be that liberal or conservative.
Case in point: The GOP primary for Wisconsin governor, where Scott Walker continues to veer farther right, even changing his positions, to keep Mark Neumann from outflanking him in the extreme right lane.
And it's beginning to look like Walker is getting even farther out than Neumann
First it was immigration. Walker took a more moderate position, but when Neumann beat him up and some of the GOP base complained that Walker was too soft, he quickly switched and became a hard-liner.
Last week it was the state smoking ban. Walker first said he didn't like it, but wouldn't commit to repealing it. But once Neumann came out for repeal, Walker followed suit.
Now, it appears Walker has found an issue where he can be even more extreme than Neumann -- human reproduction. Liberals often call the issue women's reproductive rights, but one group backing Walker and Neumann doesn't discriminate by gender. It wants to ban condoms, too.
