Affect Of Corporate and Union Money In Politics

I've been wondering what affect the SCOTUS decision to allow corporations and unions to spend unlimited amounts of money on election campaigns will be. Now they can buy as many TV ads promoting or opposing a candidate as they can afford. And they have very deep pockets! Only an organized group can come up with anywhere near as much money from private citizens. So what? So the American people mostly make up their minds who to vote for from 30 second TV ads. You can't get much information into a 30 second ad. So Americans vote without knowing very much about who they are voting for and what that candidate stands for. They really don't have a clue how that candidate will vote in office if elected. They have no idea if he, or she, will vote intelligently on legislation that will affect our lives or if they will just vote along party lines or in favor of the corporate or unions interest. Never mind if it will be good for the people of the country or if it will only further enrich the special interests who paid for those 30 second TV ads. So the chances are that in the future we, the people, will not be represented in government. It isn't like we are now, but it is even more unlikely that the lawmakers will take the good of the people into account when passing legislation.
