Eyeing a new majority, Senate Republicans are seeking to trample the immigration reform blueprint crafted by their counterparts in the House.

They are careful not to criticize the substance of the House GOP’s new set of principles by simply saying the chances of crafting a new immigration law this year are remote. Should the thorny debate continue in the months ahead, it could hurt the chances of GOP senators facing primaries and jeopardize the party’s chances of winning the majority in November.

Senate Republican Leader Mitch McConnell (Ky.) said Tuesday that he doesn’t see any way the Democratic-controlled Senate and GOP-led House will agree on immigration reform legislation in 2014.

“I think we have sort of an irresolvable conflict here,” he told reporters. “The Senate insists on comprehensive [legislation]. The House says it won’t go to conference with the Senate on comprehensive and wants to look at [it] step by step.

“I don’t see how you get to an outcome this year with the two bodies in such a different place,” said McConnell, whose seat this year is being targeted by Tea Party officials in a primary as well asDemocrats in the general election.

Democrats immediately pushed back against the GOP leader’s prediction.
