Today's installment of campaign-related news items from across the country.
* The morning after his 22-point loss in Nevada, Marco Rubio declared, "You don't win the nomination by how many states you win." That's probably not the spin his supporters hoped to hear.
* On a related note, a new Quinnipiac poll in Florida shows Donald Trump leading among Republicans in the Sunshine State with 44%. Rubio, in his own home state, is in second place with 28%, followed by Ted Cruz with 12%.
* The home-state news is better for Cruz in Texas, where a Monmouth University poll shows the senator leading among his own constituents with 38%, followed by Trump at 23% and Rubio at 21%. Note, in order to qualify for delegates in Texas, a candidate must meet a 20% threshold.
* Tennessee Gov. Bill Haslam (R) has joined the legion of Republican establishment figures endorsing Rubio's campaign. The Volunteer State's primary is part of Super Tuesday, which is now just five days away.
* With the Democratic primary in South Carolina now just two days away, Bernie Sanders is already looking ahead to other states, suggesting he's not expecting to do well on Saturday.
* A new Washington Post-Univision News poll shows Hillary Clinton leading Sanders among Hispanic Democrats, 57% to 28%. The same poll found that among Hispanic voters nationwide, 8 in 10 have an unfavorable opinion of Trump.
* John Kasich has heard the Republicans and pundits who've suggested he should end his presidential campaign, but he's tuning out the pressure. "I'm staying in," the governor told a Mississippi audience yesterday. "Everybody just needs to chill out."
* On a related note, Idaho Gov. Butch Otter (R) endorsed Kasich yesterday. Idaho's GOP primary is on March 8.
* Ben Carson believes the GOP race will take "a major shift" in his direction "very soon." Then again, Carson believes a lot of things that aren't true.
* In Ohio's closely watched U.S. Senate race, the latest Quinnipiac poll shows former Gov. Ted Strickland (D) with a small lead over incumbent Sen. Rob Portman (R), 44% to 42%.
* In retirement news, Rep. Charlie Rangel (D-N.Y.) confirmed yesterday that he'll step down at the end of this year. This morning, Rep. Matt Salmon (R-Ariz.) made the same announcement.
* Asked why Sen. Richard Burr's (R-N.C.) re-election ads reuse footage from his 2010 commercials, his spokesperson insisted the Republican chairman of the Senate Intelligence Committee is "focused on protecting our country from terrorism."
