Try this:
<$button> add tags
<$list filter="[tag[NV-senator]] [tag[NV-rep]]">
<$action-listops $tags="NV-legislator" />
</$list>
</$button>
Notes:
* The $button label is "add tags". The button actions (the $list and
$action-listops) are only performed when the button is clicked.
* The $list filter finds all tiddlers tagged with *either* NV-senator OR
NV-rep. Note that duplicates are automatically removed from the filter
results.
* For each tiddler found, $action-listops adds the NV-legislator tag to the
existing tags
* The tags list of any given tiddler are always unique, so even if you
press the button again, it will not add a duplicate tag
