People on the outside wonder where the famous checks and balances are that have made American democracy function for more than 230 years? They are still there and, up to a point, still working. For example, presidential power was checked when Trump’s ban on travellers from seven Muslim nations was halted by the courts. The ban is now mired in a legal process.

However, what the madness, abnormality or whatever you want to call it emanating from the White House does draw attention to is the real problem in American politics – the Republicans are no longer a political party but a political faction, a much more dangerous thing…

Republican factionalism has led their elected representatives in Congress to upend existing constitutional customs as thoroughly as Trump has destroyed the existing norms of presidential conduct. They have defamed the design of Madison and Thomas Jefferson by refusing to co-operate with the Democrats in any meaningful way. In fact, the idea of a pluralist society is anathema to them and they have been trying to crush it for decades.
