WASHINGTON: Mitch McConnell, the powerful Republican lawmaker who was instrumental in steering the current US shift to the political right but had a tempestuous relationship with Donald Trump, announced on Thursday he will step down from the Senate.

At 83 and in increasingly unsteady health, McConnell`s announcement on the Senate floor that he will not seek reelection next year was not a big surprise. But after serving seven terms and earning a reputation as Congress`s ruthless, master tactician, the Kentucky senator`s retirement will draw the curtain on a US political era and underline the Republican Party`s growing radicalisation.

McConnell called his four decades in the chamber `the honor of a lifetime` and said `I will not seek this honor an eighth time. My current term in the Senate will be my last.` The Kentuckian was first elected in 1984, reached the Senate Republican leadership in2007. The ultimate Washington powerbroker, he remained as party leader for a record long tenure until 2025, just as Trump came back for a second term.

Concerns have been growingaboutMcConnell`s health after repeated episodes in which he appeared to freeze during public events, as well as suffering several falls.

In addition to his physical frailty, he has seen himself increasingly sidelined by a resurgent Trump, who swept back topower in the November presidential election, demanding total loyalty from a Republican Party where dissenters have largely quit or been cowed.

South Dakota Senator John Thune, an ally, was chosen to replace him as leader of the party`s new Senate majority. Back in 2016, it was McConnell who helped Trump win his shock first election.

Throughout Trump`s often chaotic and scandalprone first term, the Senate mastermind was instrumental in advanc-ing a right-wing agenda including the confirmation of three conservative justices to the powerful Supreme Court.

The court`s ruling in 2022 to end the federal guarantee of abortion rights leaving decisions on the procedure to individual state governments was a lasting monument to McConnell`s influence.

The senator was equally effectiveinusinghishardball tactics to wreck Democratic-led legislation, earning his nickname the `Grim Reaper.

But McConnell fell out with Trump after he led attempts to overturn the 2020 election in which he lost to Democrat Joe Biden, culminating with the January 6, 2021 assault on the US Capitol.

Like nearly all other Republican leaders, McConnell soon swallowed his pride and made up with Trump. But as the second Trump presidency dawned, it became clear the veteran political general was out of step with the radical populism and isolationism gripping the party`s troops.-AFP
