The Ireland border issue is a classic example of a brexit problem that was swept under the carpet during the referendum campaign. An inconvenience to brexiteers kept out of the glare of investigation (and underplayed by remainers to boot). Brexiteers just hoping it would go away. We had all the lies about immigrants and taking back control and extra money for the NHS, but the border issue was possibly the most egregious example of all of sheer political irresponsibility and shortsightedness. It's impossible to overstate the drastic implications of no deal with a hard border, as Jim says. "We know more now than we knew then." Well the electorate does, but the brexiteers must have known all along, but they weren't telling us.
