Today's installment of campaign-related news items from across the country.
* Jeb Bush told ABC yesterday that he will support the Republican Party's presidential nominee, even if it's Donald Trump.
* Vice President Biden conceded yesterday he's unsure "whether my family and I have the emotional energy" for another presidential campaign. "The honest-to-God answer is I just don't know," he said last night.
* At a New Hampshire event yesterday, an attendee to a Jeb Bush event literally fell asleep. Soon after, the Florida Republican tweeted a picture of himself and the voter, saying she'd woken up early yesterday for a 12-hour shift.
* Gallup published new results this morning, showing favorability ratings for the Republican presidential candidates among GOP voters. The news isn't good for Jeb Bush and Scott Walker, once seen as the party's top-tier contenders.
* With Scott Walker's presidential campaign moving in the wrong direction, his allied super PAC is preparing an $8 million investment in South Carolina, home to the third 2016 nominating contest.
* The Iowa Democratic Party is expanding its use of "satellite caucuses," allowing voters to participate in the 2016 nominating process in places such as "factory sites and senior citizen residential facilities." The Iowa Republican Party said it has no similar plans.
* Rep. John Kline (R-Minn.) announced yesterday that he'll retire next year after 14 years in Congress. The Minnesota Republican represents a competitive swing district, which President Obama carried twice, and which the DCCC is confident it can pick up in 2016.
* Republican presidential candidate Carly Fiorina said yesterday that English is "the official language of the United States." For the record, there is no official language of the United States.
