If the GOP does not win a majority in the Senate, the GOP senators’ chief election strategist will get shoved into an unmarked grave, that strategist said Oct. 16.

“I’ll be in an unmarked grave in Kentucky,” Rob Collins, the executive director at the National Republican Senatorial Committee, told reporters.

But Collins is optimistic about his future because he’s confident the GOP will win a Senate majority in November — even though he and his aides have ignored their own polls that show Democratic and swing voters are strongly opposed to Democratic senators’ immigration votes.

“We’re going to win the Senate, I feel very good about that,” said Collins, whose committee isn’t supposed to pick legislative priorities or push ideological goals, but just to fund, train and elect GOP incumbents and candidates.

The unpopularity of the Democrats’ push for more foreign workers is underlined by large-scale polls conducted recently for the senatorial committee.

For example, 51 percent of unmarried women said they would be much more likely to vote for a GOP candidate who said that “the first goal of immigration policy needs to be getting unemployed Americans back to work — not importing more low-wage workers to replace them,” according to a September poll. An additional 19 percent of unmarried women said they would be “somewhat more likely” to vote for the GOP, said the poll, which was conducted for the committee by Paragon Insights.

Forty-two percent of Hispanics said they would be much more likely to support a GOP candidate who says that “immigration policy needs to serve the interests of the nation as a whole, not a few billionaire CEOs and immigration activists lobbying for open borders,” according to Paragon’s survey. An additional 24 percent of Hispanics said they would be “somewhat more likely” to vote GOP, said the poll.

In 2012, Gov. Mitt Romney won only 27 percent of Hispanic voters, and 35 percent of unmarried women, after Democrats spent months running visceral TV-ads accusing him of being hostile to Latinos and women.

The NRSC poll matches results from prior surveys, including a work-and-immigration survey by Kellyanne Conway.

Collins acknowledged that the immigration issue has grabbed voters’ attention — but suggested that the attention has declined in recent months.

“At the summertime… it was a huge national topic when you had unaccompanied [Central American] minors down at the border in record numbers and the American people were very focused on it,” Collins told The Daily Caller.

The immigration issue has come up in many Senate races, he said.

“Our campaigns have discussed it,” he said. “I think it hasn’t just been a base [voter] discussion — they’ve talked about it everywhere [and] the debates all week have been about it,” Collins said.

“So it has been a big part of the discussion, but I also think it get gets back to this notion that every state [looks at immigration] differently, like health care, like the economy,” he continued.

“Immigration has been a national issue that has been tailored to a regional and state-wide audience, and I think that our candidates have reflected a mood — not just of Republicans, but where their voters are — with regards to the issue,” he stated. “That’s why you have seen candidates have different views on it.”
