Today's installment of campaign-related news items from across the country.
* We now know which 10 Republican presidential candidates will be on the stage for tomorrow night's event -- John Kasich edged out Rick Perry for the 10th slot -- but as Rachel explained on the show last night, the entire process is fraught with controversy.
* Also note, among those excluded from the debate are the only woman in the GOP field, the candidate who came in second in the last presidential election cycle, and the two longest serving governors running this year.
* In New Hampshire, the new WMUR poll shows Hillary Clinton with a modest lead over Bernie Sanders in the Democratic presidential primary, 42% to 36%. This is similar to the WMUR poll from June, which found Clinton leading 43% to 35%.
* At the national level, a new Monmouth poll found Clinton with a far more comfortable lead over Sanders, 52% to 16%. Vice President Biden was included in the poll, and he received just 12% support.
* New Jersey Gov. Chris Christie (R) used to support a pathway to citizenship for undocumented immigrants, but yesterday, he told a New Hampshire audience, "This path to citizenship stuff is garbage."
* Apparently, GOP presidential hopefuls are each appearing in a strange, supposed-to-be-funny online video, with Louisiana Gov. Bobby Jindal (R) partnering with BuzzFeed for this new clip featuring the candidate doing push-ups.
* On a related note, Jindal won't be on the prime-time debate stage tomorrow night, but his super PAC will be airing ads in Iowa during one of the debate's commercial breaks.
* And in Pennsylvania, Katie McGinty, Gov. Tom Wolf's (D) chief of staff, made it official yesterday, kicking off her U.S. Senate campaign. She'll face former Rep. Joe Sestak (D) in a primary, and the winner will take on incumbent Sen. Pat Toomey (R) next year.
