Input: The coalition  known as the Democratic Unity Roundtable (MUD)  is considered the principal opposition to  NicolÃ¡s Maduroâs  socialist regime and includes more than a dozen political parties whose ideologies range from center-left to center-right.
 Maduro  first announced  he  would ban some opposition leaders from running in December after they questioned the legitimacy of the latest round of elections.
Other prominent opposition leaders  such as Popular Will leader Leopoldo LÃ³pez and rightful Caracas Mayor Antonio Ledezma  remain imprisoned or exiled by  the regime .
The election  which is scheduled for April  is widely expected to be rigged in Maduroâs favor  with  his regime  looking to fully consolidate  its  power on the country experiencing the worst political  economic  and humanitarian crisis in  its  history.
