DAY IN A NUTSHELL
The Republican convention gets back on track, after Hurricane Gustav blew the first day off course. President George W Bush gives John McCain his backing as Republican nominee via video-link. Joe Lieberman - a former Democrat-turned-independent senator - gives a keynote speech praising Mr McCain's character and bipartisanship. Former Senator Fred Thompson also weighs in for Mr McCain.
"John McCain is the best choice to bring our country together and lead our country forward. I'm here tonight because John McCain's whole life testifies to a great truth: being a Democrat or a Republican is important. But it is nowhere near as important as being an American."

"I know the hard choices that fall solely to a president. John McCain's life has prepared him to make those choices. He is ready to lead this nation."

"The Democrats present a history-making nominee for president. History-making in that he is the most liberal, most inexperienced nominee ever to run for president."

"George Bush enthusiastically passed the torch to the man who's earned it by voting with him 90% of the time... The man George Bush needs may be John McCain but the change America needs is Barack Obama."

The latest Gallup daily tracking poll gives Democratic candidate Barack Obama the support of 50% of registered voters, with Mr McCain at 42%, the first time Mr Obama has attracted fully half of the vote, the AFP news agency reports.
Rasmussen's daily tracking report gives Mr Obama 51% backing to Mr McCain's 45%.
Another Rasmussen poll suggests 48% of voters believe Mr McCain's vice-presidential nominee Sarah Palin is not ready to be president.
Almost three in 10 say the Alaska governor is ready and 23% are not sure.
In addition, the poll suggests she may not win over large numbers of female voters: 41% of women surveyed said she was not the right choice, compared to 36% who said she was a good one.
