Well, being that Shelby is pro choice and that Moore is pro life it might not be a bad idea that he replace Shelby. Though I like Shelby it hurt my conscience to vote for him on that point alone. Too bad he had to keep that Democrat tendency when he switched parties.
The problem I see with Moore in the Senate isn't a pro-choice/pro-life position (I'm sure other pro-life candidates can be found to run against Shelby), but whether his temperament is suited for the senate. It's that the Senate, unlike the House, is big on *decorum* and *compromise,* neither of which is Moore's strong suit. I can't imagine Moore sitting in the Senate and being quiet, not being allowed to give a speech--and a very controlled one at that, and approved by the Senate leadership--for a year or two.
If he were to run for federal office, he'd be better suited running for a House seat, where he can rail to his heart's content, give special order speeches long into the night, things like that.
