Former Rep. Charlie Dent (R-Penn.) said on Wednesday that he will be voting for Joe Biden over President Trump in November, telling CNN: "At the end of the day, this really isn't about right or left. It's not about ideology. ... For me, it's about right or wrong."

Why it matters: Dent, who represented the key swing state of Pennsylvania in Congress before retiring in 2018, is one of a number of former Republican officials who have come out against Trump during the week of the Democratic National Convention.

  • Former Ohio Gov. John Kasich, former Secretary of State Colin Powell and the late Sen. John McCain's wife Cindy are among those who have spoken at the DNC in support of Biden this week.
  • Dent said that he doesn't know if these GOP endorsements will have an impact on voters, but that there are "many Republicans" who agree with him that "we have to talk about broader principles here rather than just an immediate policy victory."

What he's saying: "For me, it's about right or wrong. Stability vs. instability, security vs. insecurity, normal vs. abnormal. That's why I'm doing this because I feel that we need to return some sense of normalcy to the function of government. We simply don't have that now. And that's why I'm going to be voting for Joe Biden for president."

  • "There are greater principles involved like the rule of law. We have to defend democratic values. And I say democratic with a small "D." A free press, an independent judiciary. These are things that are very important."
  • "And the president has been trying to undermine those things. And I think that, again, we have to talk about broader principles here rather than just an immediate policy victory."

What to watch: Dent said he thinks it's "improbable" that Trump wins Pennsylvania again because the "suburban erosion for Republicans has been dramatic since the president was elected."

The Cook Political Report on Thursday changed its forecast of Arizona in the presidential race from "toss up" to "lean Democrat," citing new polling data that shows the Sun Belt state slipping away from President Trump.

Why it matters: The rating in a crucial swing state doesn't bode well for President Trump's re-election chances. He won the state by more than 3 points in 2016.

Democratic presidential nominee Joe Biden told reporters in Delaware Wednesday he believes he would have the legal authority as president to issue a nationwide mandate to wear face masks to curb the spread of the coronavirus if needed.

Details: "Our legal team thinks I can do that, based upon the degree to which there's a crisis in those states, and how bad things are for the country," Biden said.

When he talks about Russia, Joe Biden has sounded like Ronald Reagan all summer, setting up a potential Day 1 confrontation with Russian President Vladimir Putin if Biden were to win.

Why it matters: Biden has promised a forceful response against Russia for both election interference and alleged bounty payments to target American troops in Afghanistan. But being tougher than President Trump could be the easy part. The risk is overdoing it and making diplomacy impossible.
