Rush Limbaugh has been encouraging his radio program listeners to vote for whomever is behind in the Democratic primary, to instate "chaos and disunity" among Democrats during a divisive primary battle. Limbaugh then began to advocate that his Republican listeners vote for Clinton, something the rules of the Texas primary permitted.
According to a county volunteer, one voter declared "Rush Limbaugh sent me", another "I am voting for Hillary Clinton but I want to see the Democrats implode," and a great many others mentioning Limbaugh.
Rush Limbaugh has stated that there is nothing wrong with Republicans voting in the Democratic primary, as Democrats voted for McCain in Vermont, New Hampshire, Florida and other states. "This is getting absurd. If it weren't for independents and Democrats crossing over, Senator McCain would not be our nominee!"
In Ohio, Limbaugh similarly encouraged his listeners to re-register as Democrats and vote for Clinton. Although Ohio does not use an open primary, voters who change their registration must attest that they support the principles of the party to which they switch. About sixteen thousand Ohio Republicans switched parties for the election. The Cuyahoga County Board of Elections announced that, at the urging of Democrat Sandy McNair, the cross-overs would be investigated. Later, the Ohio Attorney General's office stated that it would be hard to prosecute anyone for falsifying a change of registration, because of the difficulty of proving a voter's fraudulent intent.
Limbaugh has said that "The dream end of this [of Operation Chaos] is that this keeps up to the Convention, and that we have a recreation of Chicago 1968 with burning cars, protests, fire, and literal riots and all of that, that is the objective here."
