Can Alabama and Mississippi do what Super Tuesday failed to do - give the race for the Republican presidential nomination more clarity?

Rick Santorum heads into Tuesday's primaries coming off a big win Saturday in Kansas, where the former senator from Pennsylvania took more than half the vote in that state's caucuses.

And for front-runner Mitt Romney, the strategy seems to be downplaying expectations and hoping for a better than expected finish.
