Activists who are part of the Black Lives Matter movement have disrupted campaign rallies across the country this summer, demanding to be heard. On Friday, a group of black activists unveiled sweeping policy proposals to try to end killings by police in the U.S., and they vow to hold the 2016 presidential hopefuls accountable for their stances.

The Times' Matt Pearce has the details on the campaign:

What happens when you take Donald Trump's immigration plan to Tijuana? Times columnist Robin Abcarian found out. Trump's tough talk got a reality check, she writes.

"I challenge anyone to read Trump's immigration 'plan' and tell me how he can accomplish anything other than pushing the rest of the Republican field to the right, toward what the party's own officials have described, in so many words, as a political suicide leap."

Actress and activist Ellen Page confronted Sen. Ted Cruz at the Iowa State Fair, the Des Moines Register reports.

The exchange appears to have been about the treatment of gay people overseas. But the excerpt quoted in the paper makes it a little unclear. Nonetheless, Cruz did not appear to recognize the actress, who is best known for her break-out role as a pregnant teenager in "Juno."

Who says you can't run for the White House and for reelection to the Senate?

At a meeting of the Kentucky GOP's Central Committee on Saturday, Sen. Rand Paul will be making the case that he should be allowed to do both.

What Paul is proposing would do more than give him the safety net of potentially keeping his Senate seat should his White House aspirations fall short.

It would also push the Bluegrass State toward the front of the Republicans' presidential nominating process with a proposed early presidential caucus in March, alongside its usual mid-May primary.

Paul is seeking the change because Kentucky law prohibits a candidate from running for two spots in one election. If the committee approves the change, he could run for the presidential nomination in the special March caucus and his Senate seat in the traditional May primary.

As might be expected, the request faces a skeptical crowd back home.

One problem is cost. Estimates put the price tag for holding the early presidential caucus, in addition to the state primary, as $300,000. Others suggest that it would cost more than twice that.

Paul has promised to cover the cost, putting $200,000 in a special account and vowing to pay whatever else is needed in full.

The bigger issue, though, is what Paul would do if the proposal is rejected?

If that is the case, he would be forced to decide whether to run for one office or the other, and that would be a shake-up for both races.

And if he prevails, what happens in November? He would need to sue the state to allow him to appear twice on the general-election ballot.

The Central Committee is scheduled to meet at 11 a.m. EDT in Frankfort, Ky., for the vote.

With about 200 members, it could take a while for the decision to come down.

Over on Company Town, our colleague Stephen Battaglio has a revealing look at how Donald Trump is boosting TV news ratings.

Here's Battaglio's bottom line: "The extended coverage on cable news indicates that Trump's candidacy has transitioned from what looked like a novelty to a full-blown movement as he remains the front-runner in every poll of Republican contenders. But the ratings are likely making it an easy decision to spend more time on him."

Trail Guide was chock full of good political analysis, news, podcasts and Time magazine cover jokes. Just in case you missed it, a few highlights:

> Jeb Bush stood by his use of the term "anchor babies," prompting criticism from Democrats.

> A new poll found Hillary Rodham Clinton is looking at a trust deficit in key battleground states.

> Bush and others talked up vouchers and school choice, and talked down Common Core , at a forum on Wednesday.

> They also offered some interesting thoughts on teachers and teachers lounges.

> The Times' Kurtis Lee and Dexter Thomas talked about the fine line between heckling and activism in presidential politics in this new podcast

> Trump + magazine cover + bald eagle = Internet explosion

Being president is hard. Presidents inevitably screw up. They often pay for it.

Jimmy Carter reminded us all of that Thursday, as he offer a surprisingly direct assessment of his one big regret in life.

So in honor of Carter, we put together a list of other memorable presidential regrets. Attention, candidates, one of you will add to this list soon enough.

It's the year of the outsider in presidential politics, and Larry Lessig is testing how far outside the American public wants to go.

The Times' Cathleen Decker has this analysis of the Harvard professor's unlikely bid to take the White House -- and make point about the toxic role of money in politics in the process.

Lessig's scheme is a fascinating experiment. And in this summer of Donald Trump-size surprises, Decker writes, it can seem as though anything is possible.

"But, reality intrudes," she writes. Check out her full analysis and interview with the candidate at the link below.
