Why was the election of andrew jackson significant

Jackson's election was significant because of his posture as "the common man's" candidate.  Jackson was one of the first Presidents elected who did not have the Federalist pedigree of prior candidates.  At the same time, he did not possess the "insider" status of his opponent, John Quincy Adams.  

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
