title: Using Python to select a specific toggle_link
body: <p>The big goal is to find specific house bills.
  With this code I am trying to select the link: <code>/legislation?q=%7B%22congress%22%3A%22113%22%2C%22chamber%22%3A%22House%22%7D</code> to narrow down my search to house bills.</p>
  
  <pre><code>from bs4 import BeautifulSoup
  import urllib2
  
  soup = BeautifulSoup(urllib2.urlopen("https://beta.congress.gov/legislation")) 
  
  for link in soup.find_all('a'):
      soup_links = link.get('href') 
  
  import re   
  
  r1 = re.compile(r'/legislation(\?\S+congress\S+chamber\S+House\S+)')
  print r1.findall(soup_links)
  </code></pre>
  
  <p>When I do this I get an empty list instead of the link.</p>
  
  <p>It isn't my regular express because the following works:</p>
  
  <pre><code>r2 = re.compile(r'\S+congress\S+chamber\S+House\S+')
  newstring = '/legislation?q=%7B%22congress%22%3A%22113%22%2C%22chamber%22%3A%22House%22%7D'
  print r2.findall(newstring)
  </code></pre>
