　and　persecution　finally　made　real　their　declaration　of　independence　at　a　Philadelphia　convention　that　lasted　through　the　spring　of　1787。

The　document　they　produced　was　eventually　signed　but　ultimately　unfinished。　It　was　stained　by　this　nation's　original　sin　of　slavery；　a　question　that　divided　the　colonies　and　brought　the　convention　to　a　stalemate　until　the　founders　chose　to　allow　the　slave　trade　to　continue　for　at　least　twenty　more　years；　and　to　leave　any　final　resolution　to　future　generations。

Of　course；　the　answer　to　the　slavery　question　was　already　embedded　within　our　Constitution　…　a　Constitution　that　had　at　is　very　core　the　ideal　of　equal　citizenship　under　the　law；　a　Constitution　that　promised　its　people　liberty；　and　justice；　and　a　union　that　could　be　and　should　be　perfected　over　time。

This　was　one　of　the　tasks　we　set　forth　at　the　beginning　of　this　campaign　…　to　continue　the　long　march　of　those　who　came　before　us；　a　march　for　a　more　just；　more　equal；　more　free；　more　caring　and　more　prosperous　America。　I　chose　to　run　for　the　presidency　at　this　moment　in　history　because　I　believe　deeply　that　we　cannot　solve　the　challenges　of　our　time　unless　we　solve　them　together　…　unless　we　perfect　our　union　by　understanding　that　we　may　have　differ
