title: Regex: How to exclude trailing asterisk (when present)?
body: <p>I've got a some data like this:</p>
  
  <p><code>Scott Palk, Western District of Oklahoma*</code></p>
  
  <p>And want to write a regex (using REGEXTRACT) that matches only <code>Western District of Oklahoma</code>, without the trailing asterisk. But sometimes the data has no asterisk at the end, like:</p>
  
  <p><code>Matthew Kacsmaryk, Northern District of Texas</code></p>
  
  <p>Like the above, I want to match <code>Northern District of Texas</code>.</p>
  
  <p>Can I write one regex expression that will work for <strong>both</strong> of these scenarios? I've tried <code>'([^,]*)\*?$'</code>, but that matches the asterisk too in the first example. </p>
  
  <p>Using something like <code>'[^,]([[:alpha:]]+ ?)\*$'</code> also doesn't work. It matches just the last word, <em>and</em> the asterisk like <code>Oklahoma*</code>. Help!</p>
