Republican Senator Ron Johnson's unsuccessful threat to prevent gun regulation legislation from being considered in the U.S. Senate this week shouldn't be much of a surprise.
The National Rifle Association despises gun regulation of any kind and Johnson had over a million reasons to side with the group to kill the gun registration bill, which ended up receiving overwhelming bipartisan approval from his colleagues.
Turns out the NRA reported spending more than any other outside special interest group to support Johnson's 2010 election victory over incumbent Democrat Russ Feingold.
Four dozen SuperPACs and nonprofit groups representing the Democratic and Republican parties and an array of powerful special interests reported spending $4.7 million in the Johnson-Feingold contest. The NRA was Johnson's biggest benefactor and also spent more than any other outside group on the list - $1.18 million - or 25 percent of the total.
