In case you're still thinking that there's not much difference between the candidates because McCain isn't sufficiently pure as a conservative, here's a little something to think about, from the Weekly Standard:
Justice John Paul Stevens turns 88 in April, and by January 2009 five other justices will be from 69 to 75 years old. If Barack Obama is elected president, he will probably--with the benefit of resignations by liberal justices eager for him to be the president who chooses their successors--have the opportunity to appoint two or three Supreme Court justices in his first term, with another two or three in a potential second term.
So what kind of justices would Obama nominate? Let's start with the fact that he's been ranked as "the most liberal of all 100 senators". The most liberal; further left than Ted Kennedy, Russ Feingold, or John Kerry.
Reflect on that for a minute.
Next, Obama would abandon the traditional standard of nominating dispassionate judges who attempt to balance the scales of justice in accord with the highest law of the land. Instead, his criteria would be emotion, sympathy, and identity politics:
Indeed, in setting forth the sort of judges he would appoint, Obama has explicitly declared: "We need somebody who's got the heart, the empathy, to recognize what it's like to be a young teenage mom, the empathy to understand what it's like to be poor or African-American or gay or disabled or old--and that's the criterion by which I'll be selecting my judges." So much for the judicial virtue of dispassion. So much for a craft of judging that is distinct from politics.
The Oprahfication of this country will be complete.
Obama's constitutional activism is particularly evident on the touchstone issue of Roe v. Wade. Obama calls abortion "one of the most fundamental rights we possess" and promises to "make preserving women's rights under Roe v. Wade a priority as president." [emphasis added] He has harshly criticized the Court's 2007 ruling that the federal partial-birth abortion act (which was supported by broad bipartisan majorities in Congress, including abortion supporters like Senate Judiciary Committee chairman Patrick Leahy) is constitutionally permissible.
So, my fellow conservatives and pro-lifers, maybe you're not too crazy about McCain. Maybe I'm not, either. I said I'd never vote for him. I'm still annoyed about the McCain-Feingold bill. I know he's not as conservative as we'd like.
And to that I say: so what?
The stakes are too high to be nit-picky about it.
