...(PACs) are for political lobbying by 'special interest groups.' While there are limits to how much money a group can contribute to a politician directly, they can contribute more $$ indirectly through a PAC. PACs usually represent a particular issue, industry or interest: prison guards and law enforcement both have their own PACs; private prison corporations, prison builders & the industry also give big $$ through PACs to influence politicians and push new "tough" laws, to build new prisons and end parole, education & rehab programs. PACs are another way the PIC monopolizes our political system & profits off of crime.
