If Democrats don’t want to blow it, they should listen to him. “Sen. Michael Bennet (D-Colo.), who is mulling a 2020 presidential bid, says a plan to provide ‘Medicare for all’ and take away private insurance, which has the support of several Democratic White House hopefuls, is ‘a bad opening offer.’”

He might have blown his chances for a Cabinet post. “Fox News Channel anchor Chris Wallace elicited rare candor from acting White House Chief of Staff Mick Mulvaney when he asked Mulvaney to explain the ‘apparent hypocrisy’ of Trump’s immigration stance and use of undocumented workers at his golf resorts.”

Republicans will blow it if they rush to defend the super-rich. “The soak-the-rich plans — ones that were only recently considered ridiculously far-fetched or political poison — have received serious and sober treatment, even by critics, and remarkably broad encouragement from the electorate.”

Republicans blow it when they turn a blind eye toward President Trump’s bigotry. “[Rep. Liz] Cheney declined to criticize Trump for tweeting on Saturday, ‘See you on the campaign TRAIL, Liz!’ Some saw the tweet as a mocking reference to the Trail of Tears, during which an estimated 4,000 Cherokee died after they were forced off their land in 1838-1839.” You don’t have to be a partisan apologist all the time.

Will he blow it by being too positive? “Sen. Cory Booker has promised to run a relentlessly positive and unifying campaign, preaching love as an antidote to the nation’s ills during his first trip to Iowa as a presidential candidate this weekend. It’s a message that sets him apart in a large and growing Democratic field: Booker isn’t the only candidate talking about bringing a polarized nation together, but some of his rivals have tried to channel their party’s anger at President Donald Trump.” Well, it’s refreshing.

Sen. Susan Collins (R-Maine) sure blew it when she insisted Supreme Court Justice Brett M. Kavanaugh would uphold Roe v. Wade. “Kavanaugh’s dissent may be the real news here. He notes the supposed factual discrepancy and suggests that the court should just allow the law to go into effect. The lazy doctors could try again to get admitting privileges . . . His argument, in essence, is: Trust a government regulator with your rights. What could go wrong? This is, let’s say, an uncharacteristic argument for a conservative.”

Republicans will blow their status as a national party if they continue down their nativist path. Former New York mayor Michael Bloomberg: “Hard as it is to believe, the most xenophobic president of our lifetime is from the immigrant capital of the United States: New York City.” Sadly, there are racists all over the country.
