Not because Republicans think they can win against Hillary. They admit the chances for any Republican presidential candidate are pretty slim. They "love" Clinton because she is more conservative than the others. This is essentially what Bruce Barlett, a conservative pundit says:
Is hell freezing over? One might think so after reading recent comments from editors at National Review and the Weekly Standard, America's leading conservative magazines. Over the last 15 years, both magazines seldom have passed up an opportunity to excoriate Hillary Rodham Clinton as some kind of crypto-communist.
No more. Today, Sen. Clinton is rapidly becoming not merely acceptable to many right-wingers but possibly even their candidate of choice.
Bartlett prefers Clinton because she did not repudiate her vote for the Iraq War, which makes her a better potential commander-in-chief, in his eyes. Also she has made favorable comments about Big Business, trade and lobbyists. Obama is too liberal for Bartlett.
In other words, Barlettt favors Clinton because he thinks she would not change too much the conservative government that the Republicans built. He likes her because she would provide more of the same.
I can't think of a better reason NOT to vote for Clinton. Boy, do we need change. We need change in Iraq: we need to get out. We need change in the Middle East: we must work towards peace between Palestinians and Israelis and we must quiet the Iran-U.S confrontation that may otherwise lead to another war. We need to rebuild our reputation as a leader for good in the world. We need to restore our civil liberties at home, the liberties that Gonzales robbed from us. We need to build our economy so that all people, not only the wealthy, benefit. We need a universal healthcare system that serves all our needs.
Above all, we need change. We need to stop the ridiculous and wild personal attacks and talk to each other civilly. We need less polarization and more understanding. We need less fighting for rights and more working for the common good. We need less competition and more cooperation.
We don't need the Republican favorite, the confrontational Hillary Clinton. We need the liberal Democratic favorite, the accommodational Barack Obama.
