Fred Barnes, a bright and measured, solid conservative commentator, said this (via RealClearPolitics) at the Weekly Standard. Read it carefully.
The Roberts nomination didn't prompt conservatives to jump for joy, though he was widely praised. Cornyn called him a "solid pick." Republican Sen. Tom Coburn of Oklahoma offered no praise at all. He said the Senate must examine Roberts' "loyalty to the Constitution and its strict construction." Sounding a bit like Democratic Sen. Chuck Schumer of New York, who is sure to spearhead the opposition to Roberts, Coburn said senators have the right to ask "any appropriate question."
Social conservatives were hoping for more. No doubt they'll line up in support of Roberts when Democrats like Schumer and groups such as People for the American Way begin to attack him. But they dream of the day when there are five votes on the court to reverse the 1973 Roe v. Wade decision, which legalized abortion. Now there are only three. Is Roberts likely to join a anti-Roe bloc on the court? Probably not. (Emphasis added.)
