Sorry for all the US stuff at the moment, but it is the big pol story of the moment, and I’m deliberately tracking it in detail for the Daily Telegraph over at Brassneck. The appointment/nomination of Sarah Palin as John McCain’s running mate seems to have shaken things up nicely and caught the Democrats napping. But they have more than the not-much-better-than-evens in the polls to catch Obama on. They need to get some momentum going. Only next week’s Republican National Convention and the ensuing trend in the polls will tell us if they’ve managed a significant change in the polling tread. Meanwhile, Obama enjoys 60% of the much less volatile spread markets. The next two months will be a test of both men’s character and nerve.
