I think you're mixing her up with someone else. I have never heard of her referred to as "conservative".
She wrote a book, "America No More," decrying multiculturalism and bilingual education, which is offered as a selection by the Conservative Book Club. And she also had all sorts of bad things to say about Clinton. Here's an example, written right after Clinton's impeachment trial:
Already, for instance, the talk shows are filled with questioning about Gov. George W. Bush of Texas, the front-runner for the Republicans. He fully admits that he had a drinking problem more than a decade ago. Yet many pundits are wondering if this will disqualify him, even though there is not the slightest comparison between his old problem, now ovecome, and the eternal abuse of women by the president.
This is why, if we were smart, we would return to our earlier principles regarding personal behavior. Had we observed these, we would have seen clearly, from the very beginning, that Bill Clinton's life is not just an occasional mistake, but an entire system of character flaws so great that one problem, one revelation, one more hidden horror will inevitably be followed by another.
But I now think, after doing a google search, that I understand exactly what kind of "conservative" she is, and why she hates Bush so much, even though she defended him in the 1999 column I quoted. Not only has she written at least one article in Pat Buchanan's magazine, The American Conservative, but she also published a vicious anti-Israel falsehood in one of her columns. Here's what David Frum had to say about it:
Consumers of punditry often encounter Georgie Ann Geyer’s obsessive antipathy to Israel in their morning papers. Her antipathy is so strongly felt that it overcomes any journalistic scruples she might have. In a May 10, 2002, column, for example, she reported that Ariel Sharon had recently told the Israeli cabinet, “I control America.” The quote was a hoax that had originated in an October 2001 press release from a pro-Hamas association, the Islamic Association for Palestine. It had then been widely circulated on anti-semitic websites. Geyer reproduced this astonishing statement from an obviously suspect source without making any personal effort to check or verify it.
