There has been a lot of variability in the Republican polls for the 2008 election. Fred Thompson has been a relatively new addition to the fray. Meanwhile John McCain the early frontrunner stepped aside when Rudy Giuliani took over as the frontrunner. So just in the past 6 months, a lot has changed.
By looking at any single poll, the variability cannot be easily seen. As a result, you need to utilize a website that shows the candidates' poll numbers over time. USAElectionPolls.com has vaulted itself as one of the top websites to do this.
The web site is updated daily and provides polls from all the 50 states as well as poll trackers for how candidates are fairing over time.
