From the Arkansas to New Hampshire Senate races, to the Maine governor's race, Republicans are attacking Democrats on "amnesty," while suggesting it's the root cause of the current border crisis.
According to the Wall Street Journal, "Republicans cite the arrival of tens of thousands of unaccompanied Central American children in recent months to argue that Democrats are supporting bad immigration policy. A recent Wall Street Journal/NBC News poll found 64% disapprove of the U.S. response to the border crossings."
Until recently, immigration had surfaced as an issue only in Republican primaries, and mostly in border states, said Elizabeth Wilner of Kantar Media's Campaign Media Analysis Group, which provides research on political ads.
Two weeks ago, New Hampshire Senate candidate Scott Brown became the first GOP candidate to raise the issue in general-election ads, Ms. Wilner said.
Another GOP Senate candidate, Terri Lynn Land of Michigan, joined in last week, airing grainy images of border crossings and accusing her Democratic rival of "playing Washington politics." And Arkansas Senate candidate Tom Cotton started running a TV spot attacking Democratic Sen. Mark Pryor over immigration. "Chaos and crime. Washington made the mess," declares the ad from Mr. Cotton.
