(CNN) - What a difference 14 hours makes.
Republican Senatorial Campaign Committee Chairman John Cornyn is making clear his party is strongly standing behind Delaware Senate nominee Christine O'Donnell – a statement that is in stark contrast to the lukewarm response the party issued after her win Tuesday night.
"Let there be no mistake: The National Republican Senatorial Committee – and I personally as the committee's chairman – strongly stand by all of our Republican nominees, including Christine O'Donnell in Delaware," Cornyn said in a statement Wednesday. "I reached out to Christine this morning, and as I have conveyed to all of our nominees, I offered her my personal congratulations and let her know that she has our support."
Cornyn also pledged to inject $42,000 into the race on her behalf – a move that conflicted with reports Tuesday night that the party would not offer the political newcomer any financial support.
The check is the maximum amount the NRSC can give, but it is still a relatively meager one by political campaign standards. Ultimately, it remains to be seen how much the committee's Independent Expenditure is willing to spend on the race before November – the entity that has the discretion to dole out considerably more cash on behalf of GOP candidates.
"In the weeks ahead, we will decide where to best allocate additional financial resources among the large number of competitive races at stake this November," Cornyn also said. "While it's not in Republicans' interest to advertise our spending strategy to our opponents, it's worth noting that just yesterday, the NRSC's first independent expenditure ad aired in support of Dr. Rand Paul's campaign in Kentucky, where we firmly believe that he will win in November."
Still, the NRSC's now-upbeat town on O'Donnell is a marked contrast to its response last night, when the committee's executive director, Rob Jesmer, issued a terse congratulatory statement, but nothing more.
And behind the scenes, Republican officials were downright downtrodden about their newest nominee, making clear to CNN O'Donnell would not receive the party's support.
"Until she demonstrates some viability in the polls we are not going to have any money for her," a top Republican official told CNN's Mark Preston. "It is now incumbent on Sarah Palin, Jim DeMint and the Tea Party Express to help support her. They got her here. Now make it happen."
