Republican presidential front-runner Mitt Romney could lose a contest or two in Tuesday's three-state showdown, a series of contests that could finally yield a victory for Rep. Ron Paul or offer former Sen. Rick Santorum a chance to reclaim the title of top conservative alternative to Romney.
While Romney is perceived by pollsters and political pundits to be coasting toward the GOP nomination, Tuesday's contests in Colorado, Minnesota and Missouri are seen by the candidates trailing him as the opportunity to regain momentum and steal a bit of the front-runner's thunder.
