The pressure on those other dudes, whether they are looking at House, Senate, or presidential races, is enormous. Sen. Marco Rubio, R-Fla., a top White House hopeful, is working with senators in both parties to craft an immigration compromise–but some on the hard right say (wish?) that won’t last long. “Prediction: Rubio will bail out of the Amnesty Eight. Amnesty is toxic to his 2016 hopes,” Bryan Fischer, director of issue analysis for the faith-based American Family Association, tweeted Sunday. (His group says it has been “on the frontlines of America’s culture war” since 1977). …

Meanwhile, over in the House, anyone considering compromises on fiscal issues can look forward to an exercise in participatory democracy: A Club for Growth website called Primary My Congressman features nine Republicans characterized as “bottom of the barrel” on tax and spending issues. And these nine are just a start. “This website will provide an avenue for the general public to recommend primary challengers to those members and any other member they choose. We’ve already received hundreds of submissions and ideas!” club President Chris Chocola said in an e-mail Friday to supporters (boldface are his).

What will it take for Republicans to stand their ground against fellow Republicans? The determination to be true to themselves and the willingness to risk their jobs.
