Trump is not invincible in Republican race – but still lacks a single strong challenger<br /><br />All hope is not dead for Donald Trump’s Republican rivals, but anyone seeking to emerge as a genuine challenger must soon begin to coalesce opposition to the ex-president to slow his chase toward a third straight GOP nomination.<br />A new CNN/SSRS poll showing the ex-president’s big lead steady in the first primary state of New Hampshire, an escalation of the campaign in Iowa, and frustrations among donors over a bloated field that is splitting the anti-Trump vote are injecting new urgency into the race four months before voting starts.<br />“We’re talking about four months. Can you believe it?” the ex-president said during a trip to Iowa on Wednesday, claiming that his polling had gone up like a “rocket ship” and boasting about how he had carried the state twice in general elections.<br />This is about a lot more than a horse race. In this unprecedented election, Trump’s strength raises the possibility that Republicans could chose a candidate facing four criminal trials, who could be a convicted felon by the November 2024 election and is promising, in an outpouring of autocratic rhetoric, a presidency of retribution that would test the rule of law more than his first term.<br />This prospect is at least part of the reason for increasing scrutiny of President Joe Biden’s campaign and prospects amid concern over his capacity to repel a fearsome Trump assault and then to fully serve a possible second term that would end when he is 86.
