WASHINGTON – Americans don't like all the cash that's going to super political action committees and other outside groups that are pouring millions of dollars into races for president and Congress.

More than 8 in 10 Americans in a poll by The Associated Press and the National Constitution Center support limits on the amount of money given to groups that are trying to influence U.S. elections.

But they might have to change the Constitution first. The Supreme Court's 2010 decision in the Citizens United case removed limits on independent campaign spending by businesses and labor unions, calling it a constitutionally protected form of political speech.
