It’s certainly possible, but this article gives no particular reason in support of the idea.
Bush and Blair are two very different kettles of fish. Blair’s conversion was rumored for years. And his wife was already a Catholic. But, strangely, Blair supports abortion and homosexual activism, most unusual in a convert to the Church, since as the saying goes, converts are usually more Catholic than the Pope. Blair is apparently a cafeteria Catholic, and what his reasons were for converting are hard to say.
Bush is genuinely pro-life. I think it’s fair to say that he seems to have the Evangelical spirit, as well, and that his conversion experience was a turning from his drinking problem, among other things. The question I’ve always had with that is how you can be an Evangelical and square that with the very liberal doings of today’s Methodist church. You would need an unusual pastor and an unusual congregation, and I think such are becoming increasingly rarer in Methodist circles.
So, I don’t think the comparison to Blair makes much sense. Blair was Bush’s uncomfortable partner in the Iraq war, but otherwise was always more at home with his old friend Bill Clinton. Bush I think is, or tries to be, a real Christian of the old school.
Let's see...a man who is despised and vilified by the liberal "secular" elites because of the stands he has taken on morality and the unborn that are based on natural law. Also, believes deeply in Jesus Christ as his Savior, and is not ashamed to pray at any moment. He thanks God for his victory over alcoholism. He has surrounded himself in the White House with a bunch of Catholic advisers, and has named two men to the Supreme Court who are Catholic.
Sounds like he'd make a very good Papist to me, but what do I know?
