Last night’s Twitter conversation was dominated by Donald Trump. According to data from Twitter, Trump lead the pack with 33% of the conversation being about him. Sen. Ted Cruz followed with 25% and Ben Carson came in third with 11% of the Twitter conversation. Within the first hour of the debate, Donald Trump was also the candidate that gained the most Twitter followers, with Rand Paul in second, even though he didn’t attend the debate.

Former presidential candidate Lindsey Graham has endorsed Jeb Bush for president of the United States. He points to Bush’s foreign policy abilities, saying that he will be the best commander in chief to defeat the threat of ISIL. Following the announcement, Jeb Bush told Fox News: “Lindsay Graham is probably the most knowledgeable person on the Hill as it relates to national security, military affairs, foreign policy, and his endorsement is very meaningful.”

The Nation has endorsed Sen. Bernie Sanders for President of the United States. The announcement comes shortly after Moveon.org also endorsed the Vermont Senator. The Nation’s editors acknowledged the difficult path the Senator has to the nomination. The endorsement was clear about the importance of the independence of his campaign. The Nation had only endorsed Barack Obama and Jesse Jackson, until endorsing Sanders.

Ted and Heidi Cruz decided to liquidate their entire net worth to help fund Cruz’s Senate campaign in 2012. Cruz did not, however, disclose a $750,000 sum that later increased to $1 million, apparently were low-interest loans from Goldman Sachs and Citibank. Heidi Cruz is currently on leave from Goldman Sachs. There’s nothing wrong with the loans; the issue is the failure to disclose them. A spokesperson for the Cruz campaign said that not disclosing the existence of the loans was “inadvertent.”

The vast majority, around 70%, of the money poured into the 2016 presidential campaign cycle has come from non-campaign groups, i.e. super PACs and other groups. NBC News partner SMG Delta reviewed data on the about $150 million spent so far on advertising this cycle. The division along party lines is extremely stark. 83% of the money spent in the GOP race has come from non-campaign groups, compared to a surprisingly tiny 2% on the Democratic side.

Nate Silver’s FiveThirtyEight has released its GOP Iowa caucuses forecast, which gives Sen. Ted Cruz the best chance of winning, at 50%. The forecasters gathered data from 64 different polls to enhance the accuracy of their predictions. The model has Donald Trump with a 26% chance of winning the caucuses and Sen. Marco Rubio has a 17% chance.

Figures released by Mercury Analytics show that 20% of likely Democratic voters would defect to the GOP to vote for Donald Trump. In contrast, only 14% of Republicans would vote for Hillary Clinton in a general election. The study was done in connection with polling on the reaction to Trump’s first ad. The firm running the poll said they were surprised by how much the ad resonated not only with Independents, but Democrats as well.

Only seven candidates will be on stage for Thursday’s prime-time GOP debate hosted by Fox Business. Due to stricter criteria, both Sen. Rand Paul and Carly Fiorina were demoted to the under-card debate. Paul told CNN that he “will not participate in anything that is not first-tier.” There was talk from his campaign that some polling data would have in fact qualified Paul for the prime-time debate, but the decision had been made.

Through strategizing and being thrifty with campaign dollars, Marco Rubio will be able to reach more voters than other candidates actually spending more money. With super PACs charged significantly more for ad spots than a campaign itself, Rubio and his allies have decided to release the campaign money floodgates in a final effort to bolster support in early primary states.

In an apparent snub, presidential contender Ted Cruz has said he will not attend President Obama’s last State of the Union. Cruz is the only senator running for president, in either party, to opt out of attending the speech. Sens. Rand Paul, Marco Rubio and Bernie Sanders will all be present. A Cruz spokesperson said about the speech: “He’ll be just as disappointed in New Hampshire as he will be in the chamber.”
