As President Barack Obama considers sidestepping Congress to loosen U.S. immigration policy, a Reuters/Ipsos poll shows Americans are deeply worried that illegal immigration is threatening the nation's culture and economy.
Seventy percent of Americans - including 86 percent of Republicans - believe undocumented immigrants threaten traditional U.S. beliefs and customs, according to the poll.
The findings suggest immigration could join Obamacare - the healthcare insurance overhaul - and the economy as hot button issues that encourage more Republicans to vote in November's congressional election.
With Congress failing to agree on broad immigration reforms, Obama could act alone in the next few weeks to give work permits to up to 5 million undocumented immigrants and delay some deportations, according to media reports.
Hispanic and liberal voters would welcome that, but the online survey suggests much of the rest of the nation may not.
"If President Obama issues a jarring set of executive actions on legalization he could be handing the Senate to the GOP, including putting New Hampshire truly in play," said Republican strategist Ford O'Connell.
