US Mandatory Voting

The US voting public contains a majority of Democrats; 47% Democrats and 41% Republicans.
In order to be sure that all Democrats will vote and subsequently run the country, Pres. Obama has suggested mandatory voting for the US voting public. Since his original proposal, White House representatives have backpedaled amid a firestorm of public objection.
The U.S. Constitution basically specifies that a citizen's voting rights is a privilege providing he meets the qualifications. There is no indication in the Constitution that a potential voter has a responsibility to vote.
Sen. Rubio says that mandatory voting would be a violation of the First Amendment of free speech. Any person deciding not to vote is exercising his free-speech rights. If you force him to vote, he has no free-speech rights.
The likelihood is that Pres. Obama is also looking toward his objective of world government,, which includes elimination of the US as an independent country. If we have mandatory voting in the US, the next step is to have global mandatory voting, with an override of any specific country's vote.
