Donald Trump's military strike on the ISIS terror army in Afghanistan has pushed his approval rating to 50 per cent, up 8 points since the beginning of April.

The latest results from Rasmussen's tracking poll finds that half of likely voters in America approve of the president's job performance.

That number is higher than the 46.1 per cent who voted for Trump in the November election.

President Donald Trump has good news from the Rasmussen daily tracking poll, which now gives him a 50 per cent approval rating – better than his November election performance

Trump retweeted a headline from the Drudge Report about the Rasmussen poll on Monday

A polling average calculated by Real Clear Politics puts the president's overall approval rating at 42 per cent.

Despite his climb from 42 to 50 per cent, Rasmussen's result is still lower than American voters' measure of him following the botched rollout of his travel ban executive order in late January, when he dropped from a high of 59 per cent to 51 per cent.

Since then Trump's overall approval trend has slid steadily downward. It has been nearly six weeks since a majority said they approve of his work in the Oval Office.

Rasmussen's poll, cited often by the president, is generally more positive to the White House than others.

It uses anonymous telephone push-button and online polls, allowing voters to register their opinions without talking to another human being.

Those methods made Rasmussen's prediction among the most accurate before the November election.

Last week a Gallup poll put Trump's approval at just 41 per cent. Polls from CBS News and YouGov found 43 per cent of Americans approved.

Rasmussen published a separate poll on Wednesday that found a majority of Democrats believe Trump was not legitimately elected in November.

Overall, just 55 per cent of voters believe he won the election fairly.
