On its first day back from spring break, the Missouri Senate spent a little more than five hours debating a controversial bill that would make it a crime to coerce a woman into having an abortion.

The extent to which this kind of coersion actually happens is questionable, and proving it is problematic. The sponsor, Rep. Sen. Rob Mayer, laid the bill over after Democrats showed no signs of giving up on a filibuster.

The attention given to an abortion bill shows that the more folks promise change in Jefferson City, the more things remain the same.

Before the session, the talk was all about cooperation and getting the state's economy back on track. Now, midway through, the debate is once again about abortion.

An anti-coercion bill was introduced last year and went nowhere. Had the legislature passed it, there was a good chance then-Gov. Matt Blunt would have signed it into law.

This year, there's a good chance that Gov. Jay Nixon, a Democrat, will veto such a bill. As the former attorney general, he need only cite the legal pitfalls.

The slim chances of getting this bill signed into law make the prolonged debate even more of a waste of time.
