there is one candidate in this Democratic primary who Donald Trump said would make a “great president,” and it’s not Bernie Sanders.

Bernie is going to fight through the narrow path we have to the nomination because there is also only one candidate who believes health care should be a right for everyone in this country, that kids of all backgrounds should be able to go to college without crushing debt, and that we cannot transform a corrupt system by taking its money.

Can Bernie count on you to contribute $3 to our campaign right now as a way of saying you are still with Bernie Sanders and believe that every vote and every delegate is an important declaration of support for the values we share?

Donald Trump’s hammering away at questions of Cruz’s eligibility, given that he was born to his American citizen mother while she was living in Canada, “Trump may have something” when he levels the question about Cruz’s eligibility.

Trump might get traction out of reminding Iowa Republicans that Cruz’s given name is Rafael, which, apparently, is too “ethnic-sounding” for provincial “homeschooled” Midwestern conservatives.

If national polls are to be believed, then come November, we could face the largest wave of Republican voters in decades.

MEXICO CITY (AP) — Mexico’s government says nearly 9,000 Mexicans caught as illegal migrants in Arizona have been flown toMexico City the past two months under a voluntary repatriation program.

The Interior Department says in a Thursday statement that the migrants returned in daily flights from Tucson between July 11 and Wednesday.

The returnees took buses to their hometowns, most the poor southern states of Oaxaca, Chiapas and Guerrero.

U.S. officials say desert temperatures in the Mexico-Arizona border region soar to deadly levels in the summer, and deporting migrants to just across the border only encourages them to try again.

About 125,000 people have taken part in the repatriation program since it began in the summer of 2004.
