As Americans prepare to vote in Tuesday’s midterm elections, top sheriffs from across the country are warning: If President Barack Obama succeeds with his plans for an executive amnesty, there will be a flood of new illegal immigration into America this country the likes of which this country has never seen before.

“The law applies to you and I as citizens, and yet it appears there is no law when it comes to illegals,” Pinal County Arizona Sheriff Paul Babeu said in a statement provided to Breitbart News. “The message the President’s action will send is this: if you can get to the border, you’re home free. It completely undermines the rule of law and makes the job of every law enforcement officers – which is already difficult – impossible. We already have our hands full because the border is not secure: imagine what the situation will look like when the President gives executive amnesty to those already here. It would unleash a tidal wave of illegal border crossings, overwhelming law enforcement. It will be open season for the cartels. Again: the border is not secure now – to give a presidential amnesty would be to make matters dramatically worse for our officers who are trying to do the job the President won’t.”

Maryland’s Frederick County sheriff Chuck Jenkins said that Obama’s planned executive amnesty, if it succeeds, will turn every county in America into a border county.

Tuesday’s election, Senate Budget Committee ranking member Sen. Jeff Sessions (R-AL) wrote in an op-ed for Fox News, is a referendum on Obama’s plans for an executive amnesty.

“Every single Senate Democrat voted for the Obama-backed plan to provide immediate work permits to 12 million illegal immigrants – allowing them to compete for any job in America,” Sessions wrote, adding later in his column a direct plea to American citizens.

Sessions, speaking to American voters, wrote that “with your vote, you have the power to prove them [Washington and corporate elitists pushing for amnesty] wrong.”

“You have the power to deliver a message they won’t forget,” Sessions wrote.

Sen. Ted Cruz (R-TX) has made the same argument in recent months, after legislation he introduced that would defund and block Obama’s amnesty plans passed the House.

“President Obama has decided this election will be a referendum on amnesty,” Cruz said in early September on the Senate floor as he headed for an immigration showdown with Senate Majority Leader Harry Reid. Reid, using his majority of Democrats in the Senate, blocked efforts by Cruz, Sessions, Sen. Mike Lee (R-UT) and others to pass the bills defunding Obama’s amnesty.

Several GOP Senate candidates, like New Hampshire’s Scott Brown, Arkansas’ Tom Cotton and Georgia’s David Perdue–among others–have made stopping Obama’s amnesty a central theme of their campaign. Sessions has worked to help all three win their races, writing articles for and providing critical messaging for them in the home stretch. Cotton appears likely to win by a large margin on Tuesday, and Brown has come from behind in a big way in a race that comes down entirely to turnout. Perdue may win outright on Tuesday, but a libertarian in the race may send that contest against liberal Democrat Michelle Nunn into a January runoff.

Republican National Committee (RNC) chairman Reince Priebus, in a recent interview with Breitbart News and tele-town hall with TheTeaParty.net, promised Americans that if they deliver the Senate Majority to the GOP then Republicans will stop Obama’s planned executive amnesty.

“While I can’t speak for the legislature, I’m very confident we will stop that,” Priebus said, while adding he believes the president’s plans are “un-American.”

“We will do everything we can to make sure it doesn’t happen: Defunding, going to court, injunction,” Priebus said. “You name it. It’s wrong. It’s illegal. And for so many reasons, and just the basic fabric of this country, we can’t allow it to happen and we won’t let it happen. I don’t know how to be any stronger than that. I’m telling you, everything we can do to stop it we will.”

Sheriff Sam Page of North Carolina’s Rockingham County said America should prepare for a “surge” of illegal immigration–and the criminal activity that comes with it–if Republicans don’t succeed in stopping Obama, as Priebus promised.

“Human trafficking, drug trafficking and criminal activity are coming through our borders, but not staying near our borders – it’s getting into every part of the United States,” Page said in a statement provided to Breitbart News. “This is a public safety issue – a terrorist or any other kind of criminal may cross our borders. We just don’t know who is coming across. If the President issue his executive amnesty, you’ll see a dramatic surge of people coming in from all countries, including Central America – and again we won’t know who’s coming in: gangs, drugs, cartels, public health threats, human trafficking. We’re not catching but a small percentage of those coming across. This will place public safety in our communities in danger, and taxpaying citizens will be left picking up the tab.”

Hidalgo County, Texas, sheriff Eddie Guerra said America should prepare for a “terrible situation” if Obama succeeds in his plans.

Sheriff Tom Hodgson of Bristol County, Massachusetts, said even states as far away from the border as his Bay State are not safe.

Hodgson added that the message–and invitation–Obama is sending to the rest of the world through an executive amnesty could undermine the United States’ system of government.

“When the President of the United States is sending a message that he’s not concerned with lawbreaking, those words are the beginning of the destruction of our democracy,” Hodgson said. “When you have the President saying you can come in unlawfully without consequence, basically the President is saying to do the world: don’t respect our laws. That’s I worry about: if you don’t protect the framework of democracy, then you risk losing democracy itself.”
