That's an interesting dig from 2006 but that was eight years ago and much has changed since then.
Republicans controlled congress then in 2006 and held the WH and since then lost three elections of four.
His district in LI is liberal and King himself has for years taken the John McCain Grahmanesty positions, only attack Obama for not being aggressive enough with the military and be for amnesty and otherwise join Dems.
His old district voted for Bush (2004) and McCain (but would have been easily for Gore in 2000).
Redistricting left him a seat that Obama won over Romney 51.6 to 47.2. Making it slightly less Republican than seats held by rats Tim Bishop and Steve Isreal but still pretty Republican for NY.
The rats are not strongly challenging King, and did not in 2012 either.
These guys know when it pander when the time is right.
As Impy pointed out, Oberweis' "Enough illegal aliens come into America every day to fill a football field" campaign ad was a decade ago in 2004, when he was a private sector guy polling in 2nd place for the GOP U.S. Senate primary and desperately trying to out-conservative the 1st place guy, Jack Ryan, and distance himself from the image he had in 2002 as a social moderate.
In 2014, he's now a well known Illinois State Senator, former member of the IL GOP State Central Committee, and the GOP nominee for the U.S. Senate, running in a RAT controlled state where you have to kiss the combine's ring to get any kind of party support.
This week, Oberweis and Rauner attended a Illinois Business Immigration Coalition forum, and Oberweis begged for forgiveness and promised to be "bipartisan" in pursing "pathways to citizenship"
