<p>It’s hard to answer specifically for undergrad since the undergrad programs are taught by everyone in the department who also teaches grad programs. Here are the graduate Political Science rankings by US News: </p>
<ol>
<li>Harvard</li>
<li>Stanford</li>
<li>Michigan</li>
<li>Princeton</li>
<li>UC Berkeley and Yale</li>
<li>UC San Diego</li>
<li>Duke and Univ. of Chicago</li>
<li>Columbia, MIT, and UCLA </li>
</ol>
<p>btw Ohio State is next on that list tied for #13, so it’s not TOO far off from oxford</p>
