Although few think the congressman from Texas has a realistic shot at winning the GOP nod, he has built a strong enough base of support that he could be a spoiler — or a kingmaker.
In a muddled field, Paul could win the Iowa caucuses. While other candidates have been hesitant to commit to the state or have had trouble sustaining their initial bursts of support, Paul has been methodically building an organization and a growing corps of followers.
Over the past week, he has spent more than $600,000 on attack ads that are cutting into support for a fellow front-runner, former House speaker Newt Gingrich (Ga.). And Paul has built an organization that will allow him to remain in the race well beyond the early-voting states and amass convention delegates.
