"Republicans Crossing Over to Vote in Democratic Contests"
The New York Times reports: Even some states without open primaries seem to have experienced crossover voting. In the Pennsylvania vote on April 22, voter surveys indicated that about 5 percent of those voting in the Democratic primary were Republicans who switched their party registration; they split their vote almost evenly between the two candidates.
Here in Indiana, both Democratic candidates are sending surrogates to campaign in traditionally Republican areas they might have ignored in years past, including in Hamilton County, Indiana’s fastest-growing and most affluent county.
“We’re getting a lot of inquiries from Republicans asking how do you do it, how do you cross over,” Dan Parker, the Democratic Party state chairman, said in an interview here. “It’s been our No. 1 request for the past two months.”
Clouding the picture, however, is a campaign by Rush Limbaugh, the radio talk show host, urging his listeners to cast their ballots for Mrs. Clinton “if they can stomach it,” in order to prolong the Democratic race and weaken the eventual winner. -- Republicans Crossing Over to Vote in Democratic Contests - New York Times
