Today's installment of campaign-related news items from across the country.
* President Obama told NBC News, in a report that ran this morning, that Democrats need to recognize the possibility of a Donald Trump victory. "I think anybody who goes into campaigns not running scared can end up losing," he said. Directing his comments to Dems, the president added, "Stay worried until all those votes are cast."
* At a press conference this morning, Trump insisted that "they" -- he didn't say who "they" are -- believe he's received the biggest post-convention poll bounce "in memory." No one is actually saying that because it's not at all true.
* In Florida's U.S. Senate race, Rep. Alan Grayson (D) is facing new allegations of spousal abuse. Politico reported yesterday on the congressman's ex-wife "repeatedly" reporting accusations of domestic abuse to police "over a two-decade period."
* In light of the report, both the Progressive Change Campaign Committee and Democracy for America, which had been supporting Grayson's campaign, withdrew their support. Florida's Senate primary isn't until Aug. 30; Grayson is facing Rep. Patrick Murphy in a Democratic match-up.
* In Indiana yesterday, the state Republican Party's central committee chose Lt. Gov. Eric Holcomb to be the GOP's gubernatorial candidate in this year's election. Holcomb replaces Gov. Mike Pence, the Republican Party's vice presidential nominee.
* In Indiana, the Freedom Partners Action Fund, backed by the Koch brothers, is investing $1 million in attack ads targeting former Sen. Evan Bayh (D).
* Republican pollster Frank Luntz met with the GOP's Arizona delegation at the Republican National Convention last week. When he asked them about whether or not they support Sen. John McCain's (R) re-election, Luntz "was met with silence."
