Hassan has lauded Clinton for her plan to make college more affordable, calling her the leader “that New Hampshire families need fighting for them.” 

The Democratic governor is reportedly mulling a Senate run and has yet to announce whether she will seek a third term in office. 

“ I will continue to stay focused on New Hampshire, but I also understand that at some point I need to make decisions about 2016, and that needs to be sooner rather than later," she told the Concord Monitor.
