Republican presidential candidates debate again tonight. Says the Washington Post (which has Giuliani, McCain and Romney as front-runners):
Tonight's debate offers another opportunity for candidates in the next tiers to attract attention. It could be Sen. Sam Brownback of Kansas or former Arkansas governor Mike Huckabee challenging Giuliani or Romney on abortion, or Rep. Tom Tancredo of Colorado challenging McCain on immigration.
"Huckabee proved to be the most likable" in the first debate, GOP strategist Joe Gaylord said. "So he has the opportunity from the lower tier to have more people pay attention to him."
