A "silent swing" obviously is a fantasy. What is not is the general proposition that this is the best chance of electing a conservative in California. It's the best argument for voting for McClintock, even if it isn't enough in the end to be persuasive.
Many others are hostile towards those who will ensure that RAT control of Californica's statehouse continues. That is the certain result of conservatives sticking with Mc.
It's the nastiness, the "hostility", that is misplaced. The initial post on this thread may have been fanciful, but it wasn't obnoxious, didn't attack anyone personally, and didn't even attack Arnold. Too many people have demonized people on the other side. The McClintock supporters may be misguided or wrong, but in general, they are not your philosophical opponents. It's too bad things have sunk to this level here.
Arnold is the only Republican who would draw support from non-Republicans...
Generally, that's true. Which is precisely what could have given McClintock a chance.
...and none can win without that support.
That's where you're wrong. A conservative who can't get non-Republican support can win if Dems and Indies give a lot of support to Arnold. McClintock can only win in a three way race where someone takes votes away from the Dem, and that's what we have here.
The real problem that the McClintock supporters won't admit is that their guy just isn't a great candidate. He's plenty conservative, but he lacks the charisma that might have convinced more Republicans in the state that he could win. That's a reality that can't be changed no matter how right he may be on the issues, and no matter whether its theoretically possible for a conservative to win.
