So, there is no candidate that will support what 2/3 of Americans want? Why do you think that is true?
Here is my guess. Because instead of rejecting them out of hand and withdrawing support, and vocally advising them of such, people wring their hands and start campaigning on "it's the best we can do."
Until this white flag mentality is abandoned, we'll never have a candidate.
Because I've never heard anyone outside Tancredo take a hardline position. Who do you think the next cycle's candidate is? I don't know of anybody.
There have been some thoughtful articles recently on other websites pondering the financial meltdown of the last year, which has exposed in ways too obvious to miss, the intellectual and practical policy ascendancy of a very tiny minority of plutocrats in the financial industry over the thinking of both political parties.
That's the "it all comes together at the top" or "bipod" thesis David Horowitz has been writing and speaking about for at least a dozen years now.
It completely explains some curious deformations of e.g. both Bush Administrations' (41 and 43) policy priorities w/ respect to e.g. defense and immigration, tax cuts versus deficit reduction, and negation of Bill Clinton's spendthrift social-liberal impulses that put Slick on a diet of "mini-initiatives" and constant headline-grabbing that were the hallmark of his administration.
Slick was shocked and offended when his economic and Treasury advisors (who all came from the financial industry, esp. Bob Rubin, Clinton's second SecTreas) told him he had to keep the bond market happy, even if it meant giving up the lavish social spending increases that are the lifeblood of liberalism.
