“The president heads into his four-night nominating convention with an overall approval rating of 35%. That’s down from 43% in March but still within range of where Trump has been for much of his presidency. Where he falls within that range as Election Day nears could make a difference to his reelection prospects. His support continues to be driven overwhelmingly by Republicans, with 79% approving of his job performance compared with just 5% of Democrats” – AP.
