Donald Trump has been slammed as a “serial loser” by former New Jersey Republican governor Chris Christie, who also said the former POTUS was not fit to seek re-election. This comes on the eve of an announcement from Mr Trump where he is expected to reveal his intention to run for the White House again.Mr Christie initially endorsed Mr Trump in the 2016 primaries after withdrawing his own candidacy, however, he has now become one of many GOP politicians to criticise the 76-year-old’s leadership chances.The New Jersey politician said: “The only winning that has been done since Donald Trump has been president is for Donald Trump.”How about this? When Donald Trump won in 2016 he said we were going to get so tired of winning we would ask him to stop winning so much.”In 2018 we lose the House. In 2020 we lose the Senate and the White House.

And in 2022 we vastly underperform historic norms given inflation and gas prices and crime and a president at 40 percent. I’m tired of losing.”Mr Christie added that the party had “nominated some bad candidates, especially on the Senate side.”In last week’s midterm elections a number of candidates endorsed by Mr Trump lost out to the Democrats, such as Mehmet Oz in Pennsylvania and Blake Masters in Arizona.READ MORE: Donald Trump’s 2024 chances ‘hurt’ by mid term Republican red ripple Chris Christie is the former governor of New Jersey (Image: Getty) The Democrats have managed to hold the Senate (Image: Getty)The Republican governor of Maryland also shared his view of the controversial 45th president: “This is the third election in a row that Trump has cost us the result, and it’s like, you know, three strikes, you’re out.”The Republicans had expected to regain control of Congress easily, however, the “red wave” never materialised, with many blaming Mr Trump and his endorsements.The GOP may yet win control of the House of Representatives, as they only need six more of the remaining 19 seats that have not yet declared to be victorious.DON’T MISS:Harry was ‘respectful’ during visit to Pearl Harbour to mark Vets Day [LATEST]Queen Elizabeth wouldn’t let her hands be photographed [REVEAL]Channel migrants and asylum seekers lead to £1bn foreign aid overspend [REPORT] Vice President Kamala Harris (Image: Getty)However, the Democrats have the Senate, as Vice President Kamala Harris will hold the casting vote in a tie-break.One seat in Georgia is still yet to declare, with the Democrats set to hold an outright majority if the incumbent Raphael Warnock holds his position.At a rally in Ohio last week Mr Trump said he would be making a “very big announcement” on November 15, with many speculating he will try to run again in 2024.
