It seems the GOP wants to remain the stupid party.
Never mind the fact that John McCain, a very vocal supporter of comprehensive immigration reform who has utterly rejected the Malkin-Tancredo hard line, has clinched the nomination. It seems that some conservatives will be pushing a hard line.
It has not won elections, it cannot even reliably win Republican primaries (only winning when there are multiple candidates supporting the approach favored by the majority of Republican primary voters in a given race).
Yet they insist on it. Conservatives are clearly out of touch with the GOP on this issue.
