Two days after Clinton vowed to expand on President Obama’s executive actions to shield up to 5 million undocumented immigrants from deportation, Wisconsin Gov. Scott Walker was the only leading Republican 2016 contender to forcefully strike back, calling it a “full embrace of amnesty” that is “unfair to hard-working Americans.”…

“The waters are treacherous, which explains the muted response,” said William J. Bennett, education secretary under President Ronald Reagan and now a talk-radio host. “Not one of the campaigns, with the exception of Jeb Bush, have full clarity on where they want to go, and people are doing a lot of moving.”

Fergus Cullen, a former chairman of the Republican Party in New Hampshire, home to the first-in-the-nation primary, was even blunter, blaming his compatriots with failing to put the issue of immigration reform behind them. House Republicans last summer refused to vote on a bipartisan border control bill, approved by the Senate, that included a 13-year path to citizenship for illegal immigrants.

“Republicans’ intransigence has created an obvious opportunity for Hillary to rip off our arms and beat us with the bloody ends,” Cullen said. “She’s expertly exploiting our party’s internal problems.”
