Earlier this week, I declared Thursday the most important day of Newt Gingrich's campaign for the presidency.
At the time, the one-time frontrunner in the GOP race was surging in conservative South Carolina, where a win would propel him back into the top tier - a place he hadn't been for nearly a month.
Helped immensely by two extremely-strong debate performances this week - and an electorate very much in sync with his classic conservative credentials - Gingrich wiped the floor against his Republican counterparts today.
With 90 percent of votes counted, Gingrich carried more than 40% of the vote. Romney manage to win just 27 percent of the vote (Santorum and Paul tallied 17 and 13 percent, respectively).
*Most encouraging for the Gingrich camp should be his relative success at winning young voters.*
Gingrich came in second among young voters, failing to unseat Ron Paul as the favorite candidate of the GOP's next generation. But Gingrich still managed to earn an impressive 27% of young voters - evidence that his discussion of economic woes such as the increase in food stamp usage, homelessness and joblessness is resonating with certain young voters.
The relative success of Gingrich and Santorum (who pulled 22% of the young vote) with young voters in South Carolina highlights another major hurdle in favorite Mitt Romney's path to the presidency: Young people aren't rallying around him (which is perhaps a signal the party's youth base will never truly galvanize around Romney).
Not that Gingrich is the perfect candidate for young voters.
But, at this point, none of that matters. His campaign has persuaded many young people to give him a second look. Gingrich has wisely accepted an invitation with the Rev. Al Sharpton and other black leaders to discuss minority issues. If he can use that meeting to convince them that, while they have clear ideological differences, he's no bigot, it could win him the confidence needed to woo black voters disappointed by the Obama presidency.
As I've outlined previously, embracing minority voters - especially blacks and Hispanics - will be essential to whoever the GOP nominee is - and could propel someone like Gingrich in states like Florida, New York and Pennsylvania.
Looking forward, the former speaker of the House must translate his victory tonight into something more than soundbites - campaign contributions.
The Gingrich campaign's financial difficulties have been well-documented. He's polling well in Florida, but if he's going to stay through the winter and spring, he's got to translate tonight's victory into cold, hard cash.
Alexander: Will this decisive victory in South Carolina provoke a surge for Gingrich? And I'm not talking about in the polls - if this GOP race has proven any, it's been that polling is flawed - I'm talking about in the fundraising necessary to sustain a 50-state campaign.
