"We have to have this fight," said U.S. Rep. Mike Simpson, an Idaho Republican facing a tea party challenger next May as he seeks a ninth House term. The struggle will continue well into the next presidential race, he said.
Simpson and three-term U.S. Sen. Mike Enzi from neighboring Wyoming are chief targets of tea party and anti-establishment groups that prize ideological purity above all, even if it leads to legislative defeats. It's not enough, these groups say, that both men hold top ratings from conservative organizations such as the National Rifle Association.
The roar you hear in the distance will be the sound of banks crashing, followed by the silence of business-as-usual grinding to a halt. After that, the crackle of gunfire.
