I am the president of the Locke and Smith Foundation. The link to the Locke and Smith Award rankings for the Senate and House of Representatives is shown below. You can download the Locke and Smith 2017 Scorecard. Unfortunately, when it comes to constitutionality, the Missouri House of Representatives and Senate are a sea of red. Only four Representatives got above 50% correct voting. None in the Senate.
