Candidates and campaign staff can use Google alerts to do "oppo research" on an opponent as well as keep abreast of issues in their district.  All you need is a Google account and a few minutes to set up an alert.  Alerts are sent to your email address.

Make sure that you are logged into your Google account and then go to google.com/alerts to get started.  Instructions are shown below.  Enter your topic.  You probably don't want to get alerts more than once a day.

In the "Tom Crosby" alert above, notice that there is an alert for another Tom Crosby in a different area.  This, of course, will happen with common names.  You can "train" alerts by marking an alert item irrelevant.

Also use alerts to get a message out through social media by selecting either the Facebook or Twitter icon if you have campaign accounts on those social media platforms.

Suggestion:  create an alert for yourself, see what others are saying about you and your campaign!
