Before the candidates worry about who can beat the Democrat — and here, they're pretty much all assuming that will be Hillary Clinton — they need to win over Republican primary voters and caucus goers, and many of the candidates Thursday night were clearly trying to ignite the passions of the party's base. Unfortunately, with so many making the same pitch, it's going to be hard to accomplish that. Many analysts' pick Wisconsin Gov. Scott Walker as someone who could rise from the pack, stuck to his absolutist bona fides on abortion, but he's got loads of competition for the social conservative vote, particularly from former Arkansas Gov. Mike Huckabee, Dr. Ben Carson and, from farther back in the pack, former Sen. Rick Santorum. Mr. Walker can also point to his public employee union-busting successes in Wisconsin, but the ranks of current and former governors in this race who can boast conservative management is a long one. He emerged unscathed from the debate, but he didn't catch fire, either.
