Denied? Please. Arlen's in hot water because he sides with the Democrats 80% of the time. He's pro-choice, pro-Union, pro-Obama etc. I think the GOP is dumb to try and purge him, but let's not pretend like he's being persecuted unjustly here. If a Democrat voted the opposite of him, say in California, casting a critical vote sinking a number of Obama's big plans, you know you would support primarying him just like Democrats support primarying Lieberman (despite Lieberman following his heart or whatever).
Of course, the larger issue for the GOP is whether a true conservative who primaries a moderate is viable in PA
It's more like having an equivalent in Ohio rather than California. A hardcore liberal could easily be elected in California but not so much in Ohio; a hardcore conservative could easily be elected in Texas but not so much in Pennsylvania.
