(CNN) - There were concerns that Republican voters would participate in large numbers in the Democratic primaries in Ohio and Texas Tuesday and cause mischief, following a call by Rush Limbaugh for listeners to vote for Hillary Clinton.
Early exit polling shows 10 percent of the voters in Ohio's Democratic Primary identified themselves as Republican, along with 22 percent who said they were independents. It was the same story in Texas: 10 percent of the voters in the Democratic primary identified themselves as Republican, along with 25 percent who said they were independents.
